Error 8451 in replication status od DC


While I run repadmin /replsummary from one DC from my domain I am getting error 8451 "The Replication operation encountered a database error".

I had restarted the DC but same error.

The error occurs on my destination DC. While there are many source DCs as I can see from AD Replication Status tool output.

Check below article for possible database corruption

Please do workarounds mentioned in above article to identify cause of problem, if you unable to resolve problem, then only option left is to demote \ promote affected DC

You may need to demote DC forcefully by dcpromo /forceremoval if failed to demote gracefully

Then you need to do metadata cleanup as well. Check below articles for detailed information.
