I assume your record does not exist already.

Excelent idea. Try:

I don’t think you can do that unless you stop samba in the old server. Worth trying .

You probably refer to a DC server, not an AD server.

Bad idea. You know that already ;)

Review your member server config, just in case your missing something:

http://samba.bigbird.es/doku.php?id=samba:file-server

And post your smb.conf on the new member server and one of the new DCs would help diagnose.
