I am getting an error on a Windows 2003 domain controller that it says it cannor communicate with a dc on the network. This is a dc tyhat was demoted and removed from the system. I am now getting errors from the global catalog server that says baisicly that it can no longer communicate with this server and it is correct because this server does not exist anymore. Below you will find some of the error information that I get out of the directory services section of the event viewer

The site link bridge object CN=WestDC to York,CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=aaron,DC=local contains fewer than two sites links. The site link bridge will be ignored.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

The following site link bridge object references a site link, but that site link was not found in the Knowledge Consistency Checker (KCC) master list of site links.
Site link bridge object:
CN=WestDC to York,CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=aaron,DC=local
Site link:
CN=Hwy76 to York,CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=aaron,DC=local
This may affect the ability to generate intersite topology.

Was this box cleanly demoted, if not you may have to go and run a metadata cleanup
Also did you delete the old DC out of sites and servcies?

DCPROMO ran without errors when the DC was demoted. The KCC errors started after the demotion. I will look at The link provided when I get back to the office on Monday (off now for Easter holiday).

I have been able to resolve the problem. There were 2 obsolete site link bridge setting in the
Sites and Services
  Inter-Site Transports

I deleted the obsolete site link bridges and and the errors stopped.
