Just on my way to check out a down server (SBS 2008). We have lost Exchange and it appears there is some corruption in AD. There was some kind of power failure and the server did not shut down gracefully.

I will probably need to restore AD and Exchange. I do have SBS backup from last night before the corruption but don't see a way to do an AD restore through the backup GUI. I also have flat file backups of all the drives and directories.

Server is up but no one can connect to exchange either through Outook or OWA. There are error messages relating to AD corruption in the logs.

Any advice on how to approach this? In particular what would be the best way to approach the AD recovery. Again I can log into the server



Here are a couple of relevant log snippets:

MSExchangeIS (2772) First Storage Group: The log range read from the file "C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\E00.log" at offset 852480 (0x00000000000d0200) for 53248 (0x0000d000) bytes failed verification due to a range checksum mismatch.  

MSExchangeIS (2772) First Storage Group: Corruption was detected during soft recovery in logfile C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\E00.log.
