This will serve mainly windows machines. I am successful in serving files to the win 98's and win 95's at user level, however I am not able to connect or set up a domain or log-on with the winNT 2000's. The win 2000's see the work groups but don't recognize the domain controller, and reports a DNS error hey, You can create one smb.conf file for each machine.Means one smb.conf file serving win2000 machines and other for win95 and win98.
