I haven't done this in a while.  I don't remember all the issues.  Changing
the name of the server is likely to change the machine's sid.

You could take a  look at the net setlocalsid command to reset the new sid
back to the one that exists in your ldap database.

Take a look at the Samba How To.  Chapter 13 has a section  "Managing
Security Identifiers (SIDS)"

Another option is to modify the ldap database and replace the old sid with
the new one.  I would try the net setlocalsid command first.  This may cause
some issues with the roaming profiles.

I would recommend setting up a test domain and testing these options
properly before making changes to your production domain.
