The OS level is just for Browsing purposes. The only way to turn a PDC into
a Member server is to re-install NT (Go Microsoft).. You can, however, stop
the netlogon service, and bring up the machine you want to be the PDC. If
this doesn't work, reboot the PDC, bring up the new PDC (before the other
one boots) and the OLD PDC will freak and refuse to do any Domain Logons.

Hope this helps,


P.S. When was the last time the Gotchas.txt was updated? I have been running
Samba 2.0.5a with NT as a member of the Samba-controlled domain, using Samba
as the WINS server fine. Maybe the file is just out of date?
