I've rolled out two new domain controllers which will be replacing 2 current ones.
I've noticed a little bit of odd behaviour for replication between one new DC and one old DC.
NewDC1 replicates fine with all other DC's apart from OldDC1
OldDC1 replicates fine with all other DC's including 1 new DC apart from NewDC1
The error I'm receiving in AD Sites and Services:
The following error occurred during the attempt to contact the Domain Controller: Directory object not found
- All DC's are GCs
- Both Problem DC's are on the same subnet and same site
- Both are DNS servers
Any help would be appreciated.
