Exchange 5.5 Disaster Recovery:
***You must have a good copy of the latest edb files: dir.edb, priv.edb and pb.edb***
1. Build a new exchange system from scratch
2. Add new exchange to the domain
3. Stop ALL exchange services
4. Not Required, but highly recommended: Run exchange optimizer and put the databases on a drive other than the system drive.
For example: I have a system with 3 drives; C, D and E. during the optimization C retains only the Internet Mail Service Files, D has both the Information Store Logs and Directory Service Logs and everything else is on the D drive. The only other component I would consider leaving on C is the Message Transfer Agent.
5. Identify the location of the edb files on the new system (What drive are they on, the directory structure will be the same)
6. Copy the saved edb files as follows:
a) dir.edb to the EXCHSRVR\DSADATA directory
b) priv.edb & pub.edb to the EXCHSRVR\MDBDATA directory
7. Delete all log files from DSADATA & MDBDATA folders
8.Run the following CLI utilities:
(c:\winnt\system32) eseutil /r /ds
eseutil /r /is
eseutil /r
(c:\exchsrvr\bin) isinteg ?patch
9. Reboot system and ensure the services start.
