Windows 2003 DC isn't replicating across sites

I have a Windows 2003 DC on a remote site that I cannot get to replicate.  on my GC server it doesn't even give me the option to replicate.  on the DC at the remote site the server is showing up under the Default-First-Site-Name site and when i try to replicate it gives me "The following error occureed during the attempt to contact the domain controller WEST-DC-001: the target principal name is incorrect".   Under the sites it shows the correct site but under server WEST-DC-001 it doesn't show the NTDS Settings so i can replicate?  I have tried to do a dcpromo to remove it from AD but it doesn't allow me to do that either?  I have another site that works just fine?
