[Samba] migrating user profiles to new domain

[JJB]

Ok, we finally have our Linux PDC up and running. I'm trying to find a 
good guide to copying windows XP user profiles & registry settings to 
the newly created domain user profile. Also any utilities that could 
accomplish this. We are using local profiles. What we tried was using 
the "copy to" button to copy the user profile to the new domain profile. 
This seems to work for some users and not others. Manually copying does 
not get the ntuser.dat and other locked files. For some users (me, for 
instance) the copy to button is greyed out.

Any help and suggestions from folks who have done this would be appreciated.

Thanks,

Joel
