Hallo, i've got a problem with the migration of roaming user profiles from samba 2.2.3 to 3.0.9. (2.2.3 and a old server, 3.0.9 on a new maschine) The problem has to do with the ntuser.dat. When i log on a newly to the domain added maschine, i get the error message that the server stored profile can't be found and, because i deleted the locally cached profile on the client, that the local profile can't be found. When i delete the ntuser.dat, a new one is added from the default user's profile and the user's desktop content is lost... So i think that the old ntuser.dat doesn't fit. I read something about user sids which i didn't understand completely. If i read the sid of the ntuser.dat file with samba's profiles tool, i get a endless list of entries and i really don't know which one i should change. By the way: the maschine's and the domain's sids are the same on the new and on the old maschine. Thanks for your help, Christoph
