Currently i have 3 dc running in my company, and one of the dc has exchange 2010 running, and today i found out that the exchange DC has the below error and also checked Go to the HKLM -> System -> CurrentControlSet -> Services -> NTDS -> Paramaters. The DSA Not Writable is set to 4, the USN Rollback occurred
Error AD Replication: (8456) The source server is currently rejecting replication requests
i have no choice have to decommission the affected domain controller by using DCPROMO /ForceRemoval. but this is the exchange server, i dont think it is a good idea to decommission the DC which has exchange 2010 running, any better way to do that ? or i should resize the fsmo to the exchange dc server ?
