Im having some win2008 replication issues as follows:
I have a DC on the east coast called dt-2k8dc01 (2008 R2)
It replicates to my 2008 R2 DC’s in San Diego called: sd-ktosdc01 & sd-ktosdc02.
The San Deigo DC replicate to DT-2k8dc01 just fine; however, changes on dt-2k8dc01 replication to San Diego takes up to 3 hours.
All unplugged Nics are disabled. Only sd-ktosdc02 has R2 load balancing.
The DNS Server service & the Intersite Messaging service on dt-2k8dc01 stop after reboot. Both start up with no error If I manually start them. The DNS Event logs are clean.
Im getting event 2087 below. Any ideas?
I have event error:

Active Directory Domain Services could not resolve the following DNS host name of the source domain controller to an IP address. This error prevents additions, deletions and changes in Active Directory Domain Services from replicating between one or more domain controllers in the forest. Security groups, group policy, users and computers and their passwords will be inconsistent between domain controllers until this error is resolved, potentially affecting logon authentication and access to network resources.

1) If the source domain controller is no longer functioning or its operating system has been reinstalled with a different computer name or NTDSDSA object GUID, remove the source domain controller's metadata with ntdsutil.exe, using the steps outlined in MSKB article 216498.
2) Confirm that the source domain controller is running Active Directory Domain Services and is accessible on the network by typing "net view \\<source DC name>" or "ping <source DC name>".
3) Verify that the source domain controller is using a valid DNS server for DNS services, and that the source domain controller's host record and CNAME record are correctly registered, using the DNS Enhanced version of DCDIAG.EXE available on http://www.microsoft.com/dns
4) Verify that this destination domain controller is using a valid DNS server for DNS services, by running the DNS Enhanced version of DCDIAG.EXE command on the console of the destination domain controller, as follows:
