samba-users: [Samba] Samba/LDAP Win 7 unable to access shares

[Samba] Samba/LDAP Win 7 unable to access shares

Windows 7 can connect to the domain as a member (using wiki.samba Win 7
details) but cannot see any shared resources or connect to the machine at
all. Logs show tings start ok but fall apart pretty quickly. Anyone else
having issues with Win7 and Samba? On this network, XP, Vista and Mac all
swell :) Any pointers?

Samba (3.4.8) server on Debian Stable (Samba off lenny-backports in an
attempt to get Win 7 sorted a while back) auth'ing off a local LDAP server
running LDAP-Account-Manager
