[Samba] 'Not listening for calling name'

[Vicky Clarke]

I'm having a strange problem with samba, 2.2.3a running on an 
out-of-the-box SuSE 8.0 system. This is the first time I've set it up 
(hence the dumb questions I was asking on here a day or two ago). I've now 
worked my way through diagnosis.txt and a couple of odd netBIOS issues with 
the NT4 PDC, and at last I have some shares set up that my Windows client 
can use quite happily. However smbclient on the local machine comes up with 
the following error:

wild:~ # smbclient //wild/art -U username%password
added interface ip=127.0.0.1 bcast=127.255.255.255 nmask=255.0.0.0
added interface ip=172.17.1.3 bcast=172.17.3.255 nmask=255.255.252.0
session request to WILD failed (Not listening for calling name)
session request to *SMBSERVER failed (Not listening for calling name)

smbd and nmbd are running as daemons; this is my smb.conf:

[global]
         netbios name = SAMBA
         workgroup = DOMAIN1
         os level = 2

Can anyone help me work out what's going wrong?

Thanks in advance,
