Author: Every page in SQL Server database contains a unique object and index ID stored in its header. Corruption in object or index ID makes the records saved on that page inaccessible. Few scenarios under which the corruption can take place are improper system shutdown, virus attacks, and human errors. To overcome such situations, an easy way is to restore the data from an updated backup. But if in case, you have not created any database backup or backup falls short to restore the required records, then you will need to opt for advanced SQL Server Recovery software that can repair your database and allow you to access the records.
Consider a practical case, where you encounter the below error message when you attempt to view some records saved on a particular table:
“Table error: Page P_ID with object ID O_ID, index ID I_ID in its header is allocated by another object.”
The above error message makes the data stored in the table inaccessible. Additionally, you encounter the same error message each time you attempt to view the records saved in that table.
Cause:
The above error message can occur due to various hardware and software issues.
Resolution:
In case of hardware issues, run hardware diagnostics and try to swap the old hardware components. However, if the error message persists even after changing the hardware component, then you will need to firstly run DBCC CHECKDB command – without any repair clause-to determine the extent of corruption. After complete analyses, you will need to run DBCC CHECKDB command with a repair clause.
Note: Performing a repair will rebuild the Index(s) and can result into loss of data.
In most cases, the DBCC CHECKDB resolves your issue and makes the records saved in the table accessible. However, the above command fails and no clean backup is available, then you will need to use advanced SQL database recovery tool to repair the database and access the records saved in the table. These SQL Repair applications incorporate high end scanning methods to scan the hard drive and repair the corrupted MS SQL database. These tools are developed by highly talented data recovery experts and easily understandable without any prior technical knowledge.

Microsoft Exchange Server offers multilingual environment support to its users. You can easily access of your emails,contacts, tasks and other items in any language, which is included in its database. Every language in Microsoft Exchange Server has a unique Locale ID (LCID). This is quite helpful feature to provide access of Exchange Server in native language. But in some situations, this might might prove harmful and cause database index corruption. The situation might occur due to a number of reasons and eventually cause critical database corruption and data loss situations. Such cases require Exchange Server Recovery to be sorted out.
In a practical scenario of index and Exchange Server database corruption, when you move the Exchange Server 2000 database to a server, which does not have same LCID and then you attempt to defragment the database, index corruption is reported.
However, when load correct Local ID on new server and then attempt to defragment Exchange Server database, it doesn’t corruption the index corruption.
The LCID is a 32-bit value, which is defined by Microsoft Windows operation system that has a sort ID, language ID and reserved bits to identify the particular language. For instance, the Locate ID for English is 1033.
In these situations of index corruption, you can not access data from the Exchange Server database as the database become inaccessible or corrupt. Thus, it becomes essential to find out the cause of this issue and go for Microsoft Exchange Recovery by resolving it.
Grounds of the issue
When you move the database between computers where LCID is different, there is possibility of silent index corruption. For instance:
1. If an LCID, which is reinstalled that was previously uninstalled (or vice versa), there is the possibility of index corruption.
2. When you backup and restore database, which is generated by the computer that has LCID installed to a system without LCID installed, you might come across index corruption.
3. If you copy a database to another computer, defragment it and then copy back to original system, silent index corruption occurs.
Resolution
In order to retrieve data from damaged Exchange Server database, go for Exchange Server Recovery using third party applications. These tools use high-end scanning techniques to methodically scan the affected database and retrieve data from it. The Exchange Server Repair applications are complete safe and easy to use.

SQL Server database files are split up into different pages. The GAM (Global Allocation Map) pages represent allocation bitmaps. For each extent, there is a bit that indicates whether the extent has been allocated or not. Such pages map 4 GB of extents. A PFS (Page Free Space) page is allocation byte-map. Such pages indicate the allocation information for pages with a byte for each page and map about 7900 pages each. An SGAM page is similar to a GAM page and is bitmap of mixed extents. Such pages map 4 GB of extents. If you come across errors that suggest that any of these pages are not usable, this usually indicate their corruption and thus are required to be restored from backup. In case, if you face any backup related concerns, you need to repair them using SQL Server Recovery utilities.
For an instance, you might come across the below error in a SQL Server database:
“Page errors on the GAM, SGAM, or PFS pages do not allow CHECKALLOC to verify database ID DB_ID pages from P_ID1 to P_ID2. See other errors for cause.”
SQL Server error log records this error as error 8998.
DBCC CHECKALLOC is a database consistency check command that checks its disk space allocation structures.
Cause
Error 8998 results when either of GAM, SGAM, or PFS page cannot be used because of corruption. Since CHECKALLOC has no other way to check for range of corresponding mapped pages whether they have been allocated or not, it returns this error. Here, P_ID1 is the lower bound, while P_ID2 is the upper bound representing the affected region.
Solution
If such are errors occur repeatably, first diagnose the system for possible hardware concerns. However, to fix corruption problems, use these measures:
Execute DBCC CHECKDB command and note the repair clause thus suggested
Run DBCC CHECKDB command again using this repair clause
These measures can delete the corrupted data from database. To avoid this, you should use SQL Recovery utilities to repair the database effectively . SQL Repair software employ powerful scanning algorithms for the damaged database and repair it without affecting its integrity.

In Microsoft Exchange Server, you can perform hard recovery to retrieve missing or inaccessible data. Such recovery is performed after restoration from online backup, in case of serious database corruption. Hard recovery is the process of replaying a log file, which is similar to the soft recovery. In some cases, the hard recovery can not be completed successfully and the database remains inaccessible and unusable. At this point, you need to go for Exchange Server Recovery to get your mission critical and precious data back.
In a practical scenario, when you attempt to carry out the hard recovery of Microsoft Exchange Server, you might come across -1019 error message. After this error message, you may find the following Event IDs in Application Event Log of Microsoft Exchange Server:
Event ID: 0

Exchange Server public information store database contains all the user mailboxes, apart from the information which is required in Exchange Server environment and thus is considered most important. However, Information Store also comprises one another database called Public information store database, which manages data in public folders. Exchange database corruption requires Exchange Server Recovery.
In some of the cases, user may fail to mount the information store database and encounter an event in the application log of Event Viewer:
Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 505
Description: Information Store (2028) An attempt to open the compressed file “drive:\Exchsrvr\MDBDATA\priv1.edb” for read / write access failed because it could not be converted to a normal file. The open file operation will fail with error -4005 (0xfffff05b). To prevent this error in the future you can manually decompress the file and change the compression state of the containing folder to uncompressed. Writing to this file when it is compressed is not supported.
Or
Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 9519
Description: Error 0xfffff05b starting database “First Storage Group\Mailbox Store (EXCHANGE)” on the Microsoft Exchange Information Store. Failed to attach to Jet DB.
This problem is specifically encountered when user upgrades to Exchange Server SP3 or later. If the information store database has been compressed using NTFS file system compression.
Note: NTFS compression can corrupt Exchange database under critical situations like when the information store reaches to about 4 GB in size, in which Exchange Server Recovery is required.
Exchange Server SP3 and later versions, including Exchange Server 2003 don’t allow NTFS compressed information store to mount. These files are managed by ESE (Extensible Storage Engine) which require sector independence for log-based recovery process, which is not allowed in compressed files. Thus database corruption may result, specifically in database files, larger than 128 MB, which require Exchange Server Repair. Files, smaller than 128 MB, are automatically decompressed in Exchange Server SP3 and later.
In order to resolve the issue, we need to decompress the folders of Information store databases and logs after dismounting the database. Then, we need to carry out offline defragmentation using eseutil /d command and mount the database again. If the database comes out to be corrupt, we need to apply Exchange Server Repair or else perform the online backup of the database.
Exchange Server Recovery can be performed using Eseutil utility, but the corrupt pages will be deleted. So using commercial Exchange Server Repair software can be used which apply powerful, yet safe, scanning algorithms to repair the corrupt database.
Stellar Phoenix Mailbox Exchange Recovery is an excellent Exchange Sever Recovery software which is compatible with Exchange Server 5.5, 2000 and 2003. This Exchange Server Repair software has interactive interface and recover mailxes in PST format, usable with MS Outlook.

Exchange Server follows transaction logging system. Information Store folder is comprised of related transaction logs along with storage groups. It means that Information Store is the most critical part of Exchange Server. Number of storage groups may vary according to the requirements of organizations and Exchange Server version being used. If the Information Store suffers inconsistencies or corruption, EDB Recovery will recover lost data in the absence of online backup.
Priv.edb and Pub.edb are two critical files of Exchange Server Storage Group. These files contain user mailboxes. If these files get corrupt, Exchange Server may return 4294966095 error and Information Store service may fail to start. The corresponding event entry in Event Viewer is -1201.
Apart from EDB corruption, -1201 Event ID may also generate if log files and EDB files are on different drives and due to some issues, log files are not available. To resolve the issue, user can follow these steps:
• If online data backup is available, user can restore Information Store from it
• If Information Store backup is unavailable or incomplete, user needs to use Eseutil repair utility to perform Hard Recovery. The process requires two basic considerations: backing up Mdbdata folder to avoid further data loss and ensuring that hard disk contains sufficient free space for Hard Recovery. Mdbdata folder contains all log files and storage groups of Exchange Server. However Exchange Server Repair requires following commands to be applied:
Ø eseutil /p /ispriv /tx:\tempdfg.edb
Ø eseutil /d /ispriv /tx:\tempdfg.edb
Ø isinteg -fix -priv -test alltests
Ø eseutil /p /ispub /tx:\tempdfg.edb
Ø eseutil /d /ispub /tx:\tempdfg.edb
Ø isinteg -fix -pub -test alltests
• If problem persists, third party Exchange Server Recovery applications can be used on Mdbdata folder to repair damaged EDB files. These are the tools that can scan and repair damaged EDB files and extract user mailboxes without affecting data integrity.
Stellar Phoenix Mailbox Exchange Recovery is the most powerful edb recovery software. It extracts user mailboxes from damaged EDB files and restores them as individual PST files which can be used with Outlook. It supports Exchange Server 2003, 2000 and 5.5. It is compatible with Windows XP, 2003 and 2000.

In Exchange Server, Directory Replication is the process of breaking Active Directory into different sites. The purpose of the process is to reduce, if not totally eliminate, the traffic if the network links are low in speed. To make different sites aware about each other, the process required site connector and directory replication connector. If the process is intended to be functional, it is required that the directory service may remain logged on to the mailbox in Information Store all the time. However if Information Store service stops running for a time or database gets corrupt, Intersite Directory Replication may also stop functioning. Corrupt Exchange database require Exchange Server Recovery.
When the Information Store service stops running, application event log reports 1105 and 1106 events, like:
Event ID: 1105
Description: The internal directory replication agent (DRA) Dispatcher thread did not execute. If this message is logged more than 5 times, restart the directory.
Event ID: 1106
Description: The directory replication agent (DRA) has been trying to connect to the mail service for more than 10 minutes. Make sure the mail service is running.
These events are logged after a long time (about 20 to 60 minutes); however user first observes event ID 1171 when the problem is encountered.
• Users are required to restart the Directory Service to overcome the issue and continue with Intersite Directory replication.
• If this is database corruption that is preventing Information Store service to start, we need to apply Exchange Server Recovery procedures. Eseutil, the inbuilt repair utility, can be used for this purpose. But it will delete the corrupted pages, so instead third party applications should be used.
Exchange Server Repair utilities are the specific and safe tools to scan and repair damaged Exchange databases. The applications come with rich user interface and hence are easily usable. These software use scanning algorithms and don’t perform any data writing. Hence the applications are safe from data point of view. They extract all user mailboxes and make them usable as ever. These can be used in any logical corruption case with Exchange databases.
Stellar Phoenix Mailbox Exchange Recovery uses the most powerful scanning algorithms to repair damage Exchange databases. The software supports Exchange Server 5.5, 2000 and 2003. This Exchange Server Recovery software extracts all users’ mailboxes in PST format, which can be directly used in MS Outlook. It has a rich graphical interface.

Rollback is an important Exchange Server database operation that is useful in removing all the changes made since last commit operation. But improper use of rollback might damage the EDB file that requires Exchange Server Recovery to be performed.
An inappropriately handled database rollback operation by Exchange Server Database Engine results into database corruption. The corruption might cause the Microsoft Exchange Server Information Store Service to stop unexpectedly and shows access violation error messages.
If correct Exchange Server and Windows NT debug symbols are installed, you may find the following stack dump entries in the Application Event Log of Exchange Server:

After this behavior of Exchange Server, all of your business critical and valuable data becomes inaccessible. To overcome these problems, identify the problem and carry out Exchange Server Repair to sort it out.
Grounds of the issue
When the basic Exchange Server database engine attempts to rollback a creation of the LV (Long Value) tree on database table that is opened with exclusive access, Exchange Server database gets corrupted.
In this situation, the rollback operation is only partly successful. The corruption to the data would result as unexpected termination of Information Store Service.
How to fix this issue
There are two possible fixes to solve this problem. The first one is helpful to prevent this problem from occurring in future and the second one is to repair the corrupted database.
è Obtain the latest service of Microsoft Exchange Server 5.5.

Data Recovery is the skill of recovering lost data from corrupted storage media like hard drive, flash drive etc. Hard Drive Recovery service specifically takes care of physically failed hard drives. Hard drives undergo major development trends with respect to performance. For sure, this is making them more beneficial for the users but there are few negative sides of this development. They are as follows:
• Heat and stress: A hard drive with higher rpm (Rotation Per Minute) rating such as 10, 000 rpm, 15,000 rpm (especially used in servers and extreme gaming systems) heat up rapidly. Also, it stresses the hard drive components and due to extreme fatigue, components may ultimately fail. Time is the major concern here. More the user uses hard drive, more it gets prone to failure. That’s the reason why Data Recovery experts recommend replacing old hard drives and taking regular data backups.
• Manufacturing defects: Hard drive failures may also arise due to manufacturing defects. During the hard drive manufacturing process, if there is an undetected error in the hard drive, it is known as a manufacturing defect. For example, if the read/write head has not been fixed correctly, it may crash. Thus Hard Drive Recovery experts suggest trusting only established hard drive brands.
Data Recovery Service
These are the recovery procedures in which a failed hard drive is treated under sterilized surroundings of Clean Rooms. As the first step, Hard Drive Recovery technician examines the failed hard drive to find out the cause of crash. The facts like hard drive usage trends, cause of drive failure and hard drive state contribute a lot towards optimum Data Recovery from the affected hard drive. This information is communicated to user for getting confirmation to proceed for recovery. Once user affirms for same, recovery procedure is started which may take weeks for server recovery like of hard drives used in RAID configuration. The procedures vary as per the instance of failure. If this has been head crash, Data Recoveryengineers replace it with a compatible one. In case, platters are misaligned, technicians go for careful detachment and then recovery through a healthy drive.
Stellar Information Systems Limited is the foremost Data Recovery solution provider. The company offers Hard Drive Recovery service in all cases of hard drive failure like a head crash, natural damage or spindle failure. Stellar’s service is well known for its high quality all over the world with centers in India and US. At Stellar, failed hard drives are carefully examined and advanced tools and procedures are applied to extract data. It offers safe Data Recovery through state-of-the-art Class-100 Clean Rooms and expert team of recovery technicians.

Microsoft Exchange Storage Group contains Exchange databases, transaction log files and the associated system files. The mailbox store is comprised of two files: Priv1.edb and Priv1.stm, where Priv1.edb consists of the contents of MAPI messages and attachments along with many tables and metadata of the messages and other database objects. Backing up the Microsoft Exchange Storage Group is must for database administrators to avoid Exchange Server Repair, but attempts may fail with -613 error message.
Error -613 specifically occurs when the Exchange database is either corrupt due to the hardware related issues or some third party application conflicts with the Exchange Server application which resists the database from being backed up. The error specially occurs in Exchange Server 2000 and 2003.
The reason why -613 error messages is encountered is the way in which backup process compares the checksum value in the page header (which is recorded when the page was written to disk) to that of the page of data which is returned by the operating system. It occurs in response to the call of reading 4-KB page of data. The mismatch of the checksum values returns error messages such as -613.
We need to determine the exact cause of the problem and hence correct it. We can check the system log, run chkdsk, uninstall third party applications or replace the affected hardware. However, to resolve the current database corruption issue, we can restore the database from backup. In case, if there is no valid backup, the database can be repaired through Exchange Server Recovery mechanisms.
We can run eseutil/p, eseutil/d and then isinteg –fix commands to carry out Exchange Server Repair. But after this, the repaired database may not show stable behavior as of the deleted corrupted pages. So, this is recommended to backup the database prior running the commands, though corrupted and apply third party Exchange Server Recovery software to extract lost information. If data loss is observed after the application of commands such Exchange Server Recovery utilities can recover all precious information. These are safe applications which run powerful algorithms to repair the database and extract mailboxes.
Stellar Phoenix Mailbox Exchange Recovery software is the well known product for performing Exchange Server Repair. It is compatible with Exchange Server 5.5, 2000 and 2003. This Exchange Server Recovery software extracts mailboxes in PST format, which can then be used with MS Outlook. The procedure is safe and accomplishes effective Exchange Server Repair in all cases of database corruption.

Actually, with the service level change, Exchange server gets activated to rebuild the indexes to resist incompatibility issues. In condition that the computer name has got changed, the mentioned error messages may appear. So, for the success, there should be the service level match between the recovery server and Exchange server computer. The same problem has also been seen with the changed computer names and same service levels.

As all type of data prefer, for their protection and preventing from loss, their backup is necessary. Exchange Server, which is the highly used enterprise solution, also needs protection from being corrupt and online and offline backups offer them the best for it. Though Exchange Server repair solutions are always there to cure the corruption, but the backup is considered safe for unspent restoration. Let’s talk about Exchange server backups in brief.
Online Backup: Being the stable method of Exchange server recovery, the method is preferred for taking database as the whole. But, always remember the fact that none of the backup software which is not Exchange-aware will prove fruitful for the job.
With NTBackup.exe, the task is safe to perform as with the installation of Exchange Server, the setup makes this backup program Exchange-aware. Whereas, if you desire to use some third party software for the same, take care to have extension, else you will be in big loss.
Most of the backups are scheduled, so if the failure happens after few hours of the specified time, the transactions in the interval have the chances to get lost if the transaction logs also get corrupt.
Offline Backup: For Exchange Server like applications, which is quite dynamic in nature, the offline backup solutions are not so worth and even not practical. This has many downsides like database is required to set offline while the backup process is in place and hence it becomes completely inaccessible for the mean time.
These types of backups are preferred when you need to migrate to any other server. Here the restriction of software being Exchange-server is not there as file level backup takes place.
Now, this is not sure that at time of failure, you retain the backup in good state. EDB recovery may not be welcomed through these backups. Moreover, some of the users may have not taken the backups till. So, in any of the case, whether the backup is not fruitful or the backup has not been implied till, EDB repair is the way which can scan and repair the corrupted database.
You can apply Exchange server recovery utilities on the ashes of the database to get the valuable results. These products are quite safe and good for Exchange server repair with the great options.

With the newer versions of Exchange Server, the application may have become better in different perspective, but the problems like not mounting of Exchange database is still the same. Here, is a list of some probable causes which might be creating the problem and the severest one among them is which says that database is corrupted and needs Exchange Server repair:
Hardware Issues: With the event ID 474, you may discover that due to some hardware problems at hard disk level, the database has got corrupted and thus is failing to mount. This case needs handling through EDB recovery: either through backup after replacing the hard drive, moving the mailbox to other server or having an Exchange Server recovery help from service part of data recovery industry.
Not having the sufficient rights:
If you get Event ID 2102, 9519, 1029, 1005, 90741121, 125 or 9004, the problem is stuck with the modification of the SeSecurityPrivilege right. To fix the issue, manually assign the correct permission or you can also run Exchange setup in Domain Prep mode.
Transaction logs modified or deleted: The installed antivirus program should not have power over transaction log folder for scanning, for the reason that server crash may happen if any virus is detected in these logs due to the modification or deletion of affected logs. You may get Event ID 455 in this respect.
Database size limitation; Exchange server 2000 and 2003 standard edition sets limit of 16 GB to the database size, which might be the cause. Exchange server
considers PRIV.EDB and PRIV.STM as the total database size. As a cure, you can set the maximum database size to 17 GB by editing the registry and removing the undesired data. After this, remove this limit as this could raise the database corruption further.
Active Directory permission modified: If the information store has no privileges to be read, the database will fail to mount. The other reason could be that server object is not there in the Active Directory. So run Exchange Setup in Domain Prep mode or have correct ADS editing.
Among all, database corruption is the real issue to handle; either occurred due to hardware problems or some logical issues. EDB repair is the way which can medicate, but needs the real help.
As stated earlier also, hard disk damage like cases has way through Exchange server recovery service, while, in logical corruption, you have an alternative of using Eseutil utility for EDB recovery. But, I advise you not to use this as of its destructive nature to the corrupted pages; instead you can have easy-to-use third party applications, called Exchange Server repair software for the same.

. Now, take the backup of existing Exchange server on the test network

But, before blaming everything to the corruption extent, make sure that you have the proper free disk space available for the job to be done as this could be one of the reasons of failure.
• To defragment the Exchange database, Eseutil/d is used and this requires free space of about 110 percent of size of the database or file.
• When you need EDB recovery, through Eseutil/p, the amount of free space required may vary. Actually, this depends upon the number of pages which are corrupted. About 25 percent of the file in consideration has been calculated as an estimate for free space.
• For an integrity check via Eseutil/g, you need not to worry about the free disk space as there is no such dependence.
But before fulfilling and considering all the conditions, make sure that you can sacrifice data.
