[Samba] Connection to failed

[Reinhard Hnat]

I have a problem connecting to samba (3.0.24):

localhost ~ # smbclient -L desktop -U rh
Password:
Domain=[DESKTOP] OS=[Unix] Server=[Samba 3.0.24]

        Sharename       Type      Comment
        ---------       ----      -------
        homes           Disk      Home Directories
        data            Disk      Daten
        SuSE            Disk      SuSE Disk
        IPC$            IPC       IPC Service (Desktop (Samba Server
3.0.24))
        OJ6110          Printer   HP Officejet 6110
        rh              Disk      Home Directories
Domain=[DESKTOP] OS=[Unix] Server=[Samba 3.0.24]

        Server               Comment
        ---------            -------

        Workgroup            Master
        ---------            -------
        WORKGROUP            DESKTOP
shows the shares i have created.

But if i want to connect with smbclient the following happens:

localhost ~ # smbclient //Desktop/rh
Password:
Domain=[DESKTOP] OS=[Unix] Server=[Samba 3.0.24]
Connection to  failed



'rh' is a valid user to linux (gentoo) and i have added 'rh' to
smbpasswd. 

This is my smb.conf
