You recall I previously asked a question regarding the subject and a solution was accepted. However in my attempt to transfer the FSMO roles from thre current PDC to the new DC, i received the following error while trying to connect to the new DC.

'THE DOMAIN CONTROLLER WAS NOT VALIDATED BECAUSE THE RPC SERVER WAS UNAVAILABLE'.

Any ideas on how to resolve this issue please? I have a single domain in my forest and both DCs belong to it.

I'd just remove the 2003 server with dcpromo and then re-add it.  Something you missed in the forest prep adding it.

What do you mean an error trying to connect to the new DC?

Make sure the DC is pointing to inself for the Prefered DNS Server.

I am trying to transfer the FSMO roles to the new DC. To accomplish this I did the follwoing from the current PDC:

I opened the Active Directory Users and Computers snap-in from the Administrative Tools folder and then right-clicked the icon next to Active Directory Users and Computers and selected 'Connect to Domain Controller'' and selected the new DC. At this point I got the error.

I have ensured the DC points to itself as the preferred DNS server but the situation still persists.
