hello im trying to setup a test PDC using SAMBA 3 and used one example from samba docs and encountered this problem, by the way my test client runs on win2k prof: Windows Error!! "A duplicate name exists on the network" i can not log-in and i cannot browse my PDC and shared folders. then i run smbclient -L localhost %U on the PDC and it showed three server names, 3 workgroups and three master, all including the PDC. the other win2k clients are configured in workgroup for the meantime before i join them to the domain but this error appears. its the 1st time im trying to join the pc on the domain..... heres my sample smb.conf [global] workgroup = CUBAO passwd chat = *New*Password* \ %n\n*Re-enter*new*password* %n\n *Password*changed* username map = /etc/samba/smbusers syslog = 0 name resolve order = wins bcast hosts printcap name = CUPS show add printer wizard = No add user script = /usr/sbin/useradd -m %u delete user script = /usr/sbin/userdel -r %u add group script = /usr/sbin/groupadd %g delete group script = /usr/sbin/groupdel %g add user to group script = /usr/sbin/usermod -G %g %u add machine script = /usr/sbin/useradd \ -s /bin/false -d /dev/null %u logon script = scripts\login.bat logon path logon drive = X: domain logons = Yes preferred master = Yes wins support = Yes printing = CUPS any ideas???? thanks.. mike
