hi everyone i intend to disable netbios could your clarify the following points for me, do i put the following lines in my smb.conf on the domain controllers,member server or both ? disable netbios = yes smb port = 445 name resolv order = hosts my member server also acts as a print server and file server will they still function over port 445 ? and nmbd will no longer be needed. shadrock i should also mention that the member server is setup as a domain master browser and local master browser.
