About 4 weeks ago we demoted the last DC in one of our child domains. Everything went well, no errors occured during the demotion processand we thought everything was taken care of. Recently we created an AD notification job taht watches AD for us. Since then we're randomly started recieving the follow error on all of our remaing domain controllers:
AD replication health degraded: Directory partition DC=***,DC=net
Time of Event: 4/4/2011 2:04:00 PM
Source Machine Name: *****-DC02
Event Severity: 10
KS Name: 6470:AD_ServerHealth
Detail Message: Partition: DC=***,DC=net
Status: There is no replication partner for this directory partition.
I've used the NTDSUtil thinking maybe I needed to remove orphaned objects from AD but the it only shows our two remaining domain, the empty root forest and the final remaining child domain. Any ideas as to why our remaining DCs are still looking for the directory partition in a domain that doesn't exist anymore?
