Windows NT/2KX stores the Windows SID as an access control identifier inside
the profile file NTUser.DAT. If you do not replace the SID inside this file
with the new SID on from the new server then your users will not be able to
access their profiles - i.e.: It just will not work as you have seen.
You can recover the SID from the old system by running (for Samba-3):
net getlocalsid
You can set the SID on the new server by running:
net setlocalsid S-1-5-21-XXXXX-XXXXX-XXXXXX
Note: The SID must be the one you obtained from the old server.
Additionally, you must ensure that each user has the same UID and GID as they
were on old server.
