Hi, now I got a bit further. The problem is that in my domain, NT WKS use domain authentication which means, if my linux box (samba) does not exist in a NT domain controller, I lost. The correct error message I get is like this: session setup failed: ERRSRV - ERRbadpw (Bad password - name/password pair in a Tree Connect or Session Setup are invalid.) Are there any ways around that? Thanks Josef
