Can I demote a DC even though it is not doing NTFrs replication? NTDS replication is working fine. It is giving Jrnl Wrap errors in the NTFrs event log.
Here is the situation. Our customer has 3 servers (A, B, and C) in one domain that are all Domain Controllers. They are all running Server 2003 R2 Standard. Server A is also running Exchange 2003 SP2. We installed 2 new Servers (D and E) that are also DCs and are running Server 2008 R2. We did that Schema update to 2008 Schema on Server A and it replicated successfully. We moved the FSMO roles to Server D.
This is when we noticed that Server A was not doing NTFrs replication and had been in Jrnl Wrap error for a couple of months. I know we should have fixed this before installing the new DCs. NTFrs is working fine between the other 4 servers.
The plan is to demote the 3 old servers and shut them down. On server A we plan to uninstall Exchange before demoting it.
I want to make sure that there isn't something about the NTFrs not working on Server A that is going to make a mess out of this process.
