[Samba] Problem browsing shares "element not found"

[John]

Good afternoon,

I have a new Samba414 install on clean Ubuntu server 12.04. All working 
except I cannot browse into shares. I get "not accessible" and then 
"element not found". Using "net use" works fine - I can "browse" a share 
that has been attached to a drive letter but I cannot browse the UNC 
path. That is to say

NET USE P: \\MYDOMAIN\public
works, and browsing "P:" works. Browsing "\\MYDOMAIN\public" does not 
work but browsing "\\MYDOMAIN" does.

I can browse \\MYDOMAIN\sysvol and \\MYDOMAIN\netlogon shares.

I cannot browse \\MYDOMAIN\public or \\MYDOMAIN\myuser (home folder)

The Windows error text reads

\\server\username is not accessible. You might not have permission to
use this network resource. Contact the system administrator of this
server to find out if you have access permissions.

Element not found.


Again, this is a clean vanilla install of 414 (downloaded source 
yesterday from samba.org) built on a fresh Ubuntu 12.04 following the 
instructions in the Samba wiki.

Any suggestions what I may have missed?

 From irc today, I have added "browsable = yes" but it made no difference,

Samba config:
