Hello everyone, I am having some replication issues on my domain that I would like to verify before I take the appropriate steps listed in the Microsoft Tech articles. I am running in a 2 DC network both running 2008 R2 both are Global Catalog Servers. I am having a tough time deciding on which DC I should take down and make the appropriate fixes / changes to. For the purpose of this question I will name my DC's DC-01 and DC-02. On DC-01 Checking the error logs I am receiving 3 separate Event ID error 467 - Database Corruption. On DC-02 I am receiving the Event ID 1084 Error Value: 8451 indication database error, it does keep showing one specific object that for some reason I cannot seem to remove manually. I have attempted to perform a remove lingering objects which receives an error. Below is the logs from my attempt to remove the lingering object and my repadmin /showrepl logs. Replication from DC-01 to DC-02 is not working, but replication from DC-02 to DC-01 is. My questions is should I take down DC-01 and perform the database integrity / fixes or DC-02? Also any other steps anyone can suggest where I may not need to take down the service on my DC's would be appreciated, the staff around here is VERY weary when it comes to any of our machines having any downtime. Thank you!
When I attempt to run a repadmin /removelingeringobjects I receive a : (this don't work if i change these around either)
repadmin /removelingeringobjects af01e71d-2516-42ca-8560-6c4f643c5b51 64af9410-df22-4b7e-8da3-942cdfce5a92 CN=Deleted Objects,DC=contoso,DC=com
