Hello, I came across the PDC conversion docs listed here: http://www.longfamilyusa.net/samba/pdc-conversion.html I have a couple of questions that maybe someone here can answer: 1. If I have Windows XP Pro clients as part of the domain, will taking over the domain without applying the SignOrSeal patch or any changes to the workstations work? 2. I have printers setup on my Win2K PDC right now and I would like to keep printer spooling on this machine. Is there any problem with me making that PDC a member of the Samba domain instead of a controller? I read that I do not really have the change the SID on this machine. Thanks for any help. Viraj.
