[Samba] can't smbmount a Windows share

[Pablo Graziano]

Client OS: Slackware 10.2
Server OS: Windows 2003 Server sp1
Samba version: 3.0.20

Actually, it will mount, but I have to way of viewing or browsing the 
mounted contents.

Here are the commands and their status:
smbmount //192.168.0.1/share /mnt/share -o 
ro,username=administrator,password=secret  (successful)
ls /mnt/share  (fails with access denied message).

So once it's mounted, can't do a thing with it. Very frustrating.

I've run into a few users on the linux forums with the exact same issue, 
but no solution that we've found yet.

Notes:
I am logged in as root on Slackware.
linux box is a member of the domain.
authentication succeeds.

Any ideas would be much appreciated.

Thanks in advance to all helpers
