Dear All,
We have a Windows Domain Environment on our Network. And 3 domain controller on default site (head office) and two other DC’s on remote sites.
Last November I have added a new domain controller to default site (where other 3 domain controllers are located) and was getting errors related to replication after few days. In every DC I got event ID 1864 saying directory partitions are not replicating on one DC.
And I couldn’t see newly added DC on “ repadmin /showvector /latency DC=domain,DC=Com “ output on every other DC’s. Same time was started to getting errors on authentication related functions in Domain.
So then I forcefully demoted the newly added DC and did a metadata cleanup. Then all errors disappeared and authentication related function became back to normal.
Then to fulfill my early requirement I freshly installed and promoted one other server as new DC. But unfortunately I am facing same scenario as earlier. Also I noticed any changes I am doing on other DC’s are not replicating to New DC. Existing DC’s are replicating well between themselves and I can’t find any issues on those and my newly added second DC also not replicating with exiting environment. Seams something goes wrong some ware which I can’t find. Please assist.
Pls. note bellow information’s that will may be required.
