Hi All

We recently have a DC which failed to operate normally and unable to =
demote normally. Therefore I follow the steps show in =
http://support.microsoft.com/?id=3D216498 to remove all its relevant =
data from the AD. Everything seems working fine except the following =
replication errors being logged periodically. I remember before the =
failed DC was removed from my DNS server manually, the address =
41991cc7-779a-4d4c-9137-17bed1fcb075 is referring to the removed DC. I =
have tried to look through our AD everywhere with adsiedit but failed to =
locate the above anywhere. I also removed all the relevant failed DC =
records with Active Directory Sites and Services. Does anyone have any =
ideas where else should I look to have this replication task completely =
removed. Normal replications can be done between all DCs.=20

Hope someone can help me with this.
