I keep getting repeats of the following Events in my Directory Services Event Log: Event ID: 1865 "The Knowledge Consistency Checker (KCC) was unable to form a complete spanning tree network topology. As a result, the following list of sites cannot be reached from the local site..." Event ID: 1925 "The attempt to establish a replication link for the following writable directory partition failed. ..." -- Event ID: 1566 "All domain controllers in the following site that can replicate the directory partition over this transport are currently unavailable...." -- Event ID 1311: "The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition. Directory partition: CN=Configuration,DC=mydc,DC=mydomain,DC=edu There is insufficient site connectivity information in Active Directory Sites and Services for the KCC to create a spanning tree replication topology. Or, one or more domain controllers with this directory partition are unable to replicate the directory partition information. This is probably due to inaccessible domain controllers. -- All of the Domain controllers are still allowing users to log on, which is why I'm limping through the last week and a half of the Quarter. I believe the problem occurred because I restored my PDC from a ghost image of the day before at the end of march because of a problem the server had with a windows update that I couldn't get rid of. And ever since replication seems to have been working but my guess is it's only been working 1 direction. My PDC receives updates from another DC in the site and that has worked. But replication from my PDC back to that DC has not. Although this last week replication has just given up all together.

I have 4 domain controllers in 1 domain. When I'm on one of the 3 DC's that is not the PDC and I try to connect to the PDC it tells me I'm not authorized. I get this when trying to connect to the PDC's AD users and computers, DNS, or even a file share. I can however connect to any of these services using the IP address. This is strange because all DC's can ping each other and resolve the IP addresses from the names just fine and I don't seem to be having any DNS issues. The 3 DC's (not the PDC) can connect to each other just fine. I'm pretty sure I'm going to need to remove 1 or more of the DC's from the domain and re-introduce them. I'm just trying to figure out if I should remove the PDC or remove the other 3 DCs.
