Setup:
SRV1 = 2003 R2 domaincontroller
SRV2 = 2003 R2 domaincontroller with Exchange 2007 SP3
Scenario:
After some sort of disk crash on SRV2 it reports event ids 1084 and 2108, and isn't synchronizing with the other domain controller anymore. E.g. I have to reset a users password on both SRV1 and SRV2, however mail flow etc. is working fine.
After the crash I created a virtual thrid domaincontroller and set it to only replicate -from- SRV1, just in case..
Possible solution?
The crash happened around 25-26th of April, and my latest full backup of the server was on April 16th. Is it possible to restore system state from April 16th to the SRV2 DC/Exchange-server in question, and will it then synchronize with the other DCs rightfully afterwards? WITHOUT losing any AD/Exchange data?
Could I simply copy the NTDS.DIT from a working domain controller?
I have found some documents regarding actually demoting the domain controller functionality of a DC running Exchange 2007, could this be my best option?
Fresh install of Exchange 2010 on a new server and start migrating? This is last resort because we may very well be moving to Office 365 within a few weeks.
What other options do I have?
