Just copy (use tdbbackup for safety if you can't stop Samba) all the
tdb files and put them in the same spot on the new server. That is the
easiest way to do this.
My guess is that the domain sid has been re-randomised on the new
server. Dump that with 'net' (I forget the subcommand) and force it in
again (it is stored in a host-name specific key in secrets.tdb).
