The NT4 domain name is actually not recorded anywhere in Samba's DBs,
just in the workgroup parameter in the smb.conf.

So while your joined domain members won't be happy (you will need to
rejoin), you can just change it.  Just make sure the domain SID stays
the same, it should (because it will fallback to the 'machine sid' that
already has that value), but see

net getdomainsid (to get the current one/check the new one)
net setdomainsid (if you need to reset it)

I hope this helps!
