I have a VM lab 2008R2 forest with 2 DCs, 2 sites. I've been working with the site 1 only for a long time and then brought up the site 2 DC. I had to change the VM NIC, and a first boot didn't have connectivity with DC1. It prompted me to change the admin password, and then I found once on the network it has been unable to "contact" DC1. I can telnet to DC1 ports 389, 3268, 88 , but the services that contact DC1 fail along with repl. I believe I'm getting a Kerb access denied. My thoughts are that it's sending the wrong account info when getting the Kerb ticket, or possibly related to tombstone. Among other things, I've done this, http://support.microsoft.com/kb/288167/en-us. It hasn't helped. Below are some of the errors. Any help is appreciated. Pardon if I'm posting in the wrong place.

Description:
The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition.
Directory partition: CN=Configuration,DC=Dom1,DC=com
There is insufficient site connectivity information for the KCC to create a spanning tree replication topology. Or, one or more directory servers with this
directory partition are unable to replicate the directory partition information. This is probably due to inaccessible directory servers.
User Action
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 directory service that contains the directory partition in this site from a directory service that contains the same directory
partition in another site.
If neither of the tasks correct this condition, see previous events logged by the KCC that identify the inaccessible directory servers.
