When you mean register the client, are you meaning "Join the Domain"? Unless I am mistaken, I believe the machine account that you had to create using smbpasswd creates the SID in the smbpasswd file, if you copy that file over to the new server, and also copy over all the netlogon information, profiles and such. Then you should have no issues and it will be "transparent" to the clients. I believe that the "Registering" process that the workstation goes through when "creating" a machine account on the server is basically negotiating the SID from the server and then pulling that into its own registry. If I understand correctly, all of the Samba files, smb.conf, smbpasswd and the related accounts you create in the UNIX passwd/groups files act as the PDC you are running. Theoretically, you should be able to take those files anywhere, fire up the Samba service and be up and running with an exact duplicate of the original Samba PDC, right down to the SID of the individual workstations and user accounts. Someone please correct me if I am wrong, because then I will have more work cut out for me when I build my Samba BDC. Regards, Robert Adkins II IT Manager/Buyer Impel Industries, Inc.

But I don't know how can I register the client again on the new server without to generate a new profile on client side? So, can I do this somehow, or should I just create them again on the Samba server and after the clients generate a new profile just set every programs again? Thanks!
