KCC errors, what else?

Hi, let me know tips on resolving these KCC errors I see repeatly in the logs:

Event Type:      Error
Event Source:      NTDS KCC
Event Category:      Knowledge Consistency Checker
Event ID:      1311
Date:            9/17/2012
Time:            3:19:42 PM
User:            NT AUTHORITY\ANONYMOUS LOGON
Computer:      dc1
Description:
The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition.
 
Directory partition:
DC=domain,DC=domain,DC=domain,DC=domain1,DC=local
 
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.
 
User Action
Use Active Directory Sites and Services to perform one of the following actions:
- Publish sufficient site connectivity information so that the KCC can determine a route by which this directory partition can reach this site. This is the preferred option.
- Add a Connection object to a domain controller that contains the directory partition in this site from a domain controller that contains the same directory partition in another site.
 
If neither of the Active Directory Sites and Services tasks correct this condition, see previous events logged by the KCC that identify the inaccessible domain controllers.

I would start with checking the subnet associated with this site.

Make sure you can communicate with that subnet.
