Hello Andrew,
I have Upgrade my Domain from NT4 to AD.
Domain SID is a different one. I try to set this to the new one.

old pdc:
net getdomainsid

new dc1:
stop samba ; net setdomainsid [copy-from old]; start samba

Domain SID is still the "new one".
User SID are also different when I look with "rpcclient $> lookupnames".

Can this be a Problem, when I unjoin and rejoin all workstations to Domain?
