For one reason or another, there is a missing NTFRSSubscriber object in AD for a particular domain controller, which is causing SYSVOL replication to fail for that DC. We have 10 DCs and replication between nine of them is fine, with just the one that is missing the NTFRSSubscriber object causing a problem. Obvious problems are as you would expect, e.g. NETLOGON share and group policy not replicating properly.
I've used FRSDiag to troubleshoot this and I've read the MS articles on how to replace these objects and the architecture of FRS so I'm comfortable with what I need to do to fix this. I've also tested it several times in my test lab successfully. I've read these links:
The only issue I have is that this problem has very likely been around for a long time and I don't know (and cannot test) the implications of bringing a server back into the SYSVOL replication after being out for so long.
Does anyone have any practical experience of this situation?
I have system state backups, GPO backups and copies of the NETLOGON scripts that I need.
