Forensics & Computers

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.
