What is the exact error you are getting? Have reverted the snapshot(chackpoint)?
Will SzymkowskiSenior Solution ArchitectCommented:
You should NOT be doing snapshots on the production Active Directory environment. If you are reverting changes back that have already been applied this is going to skew replication with other DC's in your environment. Even if you only have one DC this will also create issues with computer objects as well as the passwords could have been reset so you might run into trust relationship issues between the computer objects and the domain.

Make sure that the Active Directory Services are stated and also check the logs as well to get more details on what is happening.

You will also want to run the following commands as well.
Repadmin /replsum
Repadmin /showrepl
Repadmin /bridgeheads
DCDiag /v
