msdtc is causing my cluster to be unavailiable via it's virtual na

I have windows 2003 sp1 running in a 2-node cluster. The cluster is running
sql sp4. I tried failing over my cluster after a windows update and i'm not
sure if that's what threw my server's off or something else. But here's the
situation. I currently have the cluster group running on node 2, the msdtc
running on node 1 and the sql group running on node 2. When i move the msdtc
group to node 2 (ie.. the server which should be running all services)i cant
ping the sql virtual server by name or ip. I am however able to contact the
individual servers via their names sql1 and sql2. So basically i lose my
connection to the virtual sql server throughout my network when the msdtc is
running on the same server. Is there an update? upgrade? to the msdtc or
anything else i can do to fix this issue?
Ohh yes and there's no errors in the event log.
What are the Resource Group names, Resource Network Names, and Resource IP
addresses? What other resources a apart of each group?
Sounds like a DNS registration issue. Does the SQL Server group go offline
or fail over when the MSDTC group is moved to node 2?
Sincerely,
Anthony Thomas
