samba - Sep 2002 - Win2k: Could not find network path

Hi there

I have a LAN with a Linux and a Win2k Computer, using DHCP to connect via 
Cablemodem to the Internet. So, we don't have fix (private-) ip's. We
receive
them via the DHCP-Server when starting up the Computers.

Now i've setted up samba on my linux (Suse 8.0) computer to share some files
(Via NetBIOS on Win, i think). 

With my current configuration i can see all my shares using smbclient on my 
machine. But the Win2k Machine isn't accessible. On the Win2k Machine on the
other Hand, i see my linux-host but i can't access it, a message, telling 
"\\blubb is not accessible, the network path was not found" appears.

I've allready upped the Registry-Key (PlainPassword). So this couldn't
be it.
Also the Users and Passwords are the same on the Win2k machine, the linux 
machine and on samba.

I really hope, someone can help me. After searching around for about 1 day, i 
didn't find a solution for this problem.

smb.conf:
[global]
        workgroup = TKS6
        netbios name = BLUBB
        security = DOMAIN
        encrypt passwords = Yes
        smb passwd file = /etc/samba/smbpasswd
        map to guest = Bad Password
        null passwords = Yes
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        character set = ISO8859-15
        os level = 0
        preferred master = False
        local master = No
        domain master = False
        dns proxy = No
        guest account = Brian
        printing = lprng
        veto files = /*.eml/*.nws/riched20.dll/*.{*}/

[homes]
        comment = Home Directories
        read only = No
        create mask = 0640
        directory mask = 0750
        browseable = No

[share]
        comment = Writeable Directory
        path = /home/share/
        read only = No
        create mask = 0750
        guest ok = Yes

[printers]
        comment = All Printers
        path = /var/tmp
        create mask = 0600
        printable = Yes
        browseable = No

Thanks in advance
