[Samba] smbtree on localhost

[Marc Weber]

Hi. 
tstparm /etc/samba/smb.conf shows some directories..
but smbtree doesn't show anything at all (from my samba server on
localhost) what might be the reason?
Do I have to open some ports? Using smbtree I can see other shares of
WinXP servers.

server string="server"
workgroup="mygroup"
netbios name="hobbit"
