[Samba] Can't connect to share

Hi all,
I'm trying to check for the existence of a particular share on a win2k 
server. The share has these permissions, Read & Execute, List Folder 
Contents and Read for the default username. The default username does not 
have a password. The error i'm getting is thus:

#smbclient //bashir/logon -U default_user -W lab_domain -I 131.181.xxx.xxx
added interface ip=131.181.xxx.xxx bcast=131.181.xxx.xxx nmask=255.255.255.0
Password:
Anonymous login successful
Domain=[lab_domain] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager]
tree connect failed: NT_STATUS_ACCESS_DENIED

(IPs and sensitive information removed/modified)

Looking at the "Anonymous login successful", I assume that i'm getting some 
sort of connection then being kicked off for some reason.

I've had a google around and checked previous mailing list at 
au1.samba.org, and found previous questions along similar lines, but no 
answers.

Am I just missing something obvious?

TIA,
