samba - Aug 2004 - Most odd -> Different domain permissions depending on workstation?

I've had a bug crop into my Samba test environment which I am not quite sure
how to debug. Depending on which workstation I use a specific ID at, some
workstations it has the correct permissions to
network shares, at other workstations it can NET USE but trying to change to
that drive letter returns "Access Denied" yet I can UNC make/remove
files and dirs to those same shares.

Any suggestions on where to begin looking?
