samba - Feb 2006 - Problem with netbios names

hi,
i've got big problem with samba, which acts as a fileserwer in company i
work for. it's configured to be LMB and DMB and according to logs, it
wins all elections. 
the problem is: i offer vpn access for few employees. one of them works
with advanced excell (mainly) macros, which are linked across samba
shares. he decided to recreate our shares structure on his home computer
to test changes before making them on serwer, which is generally good
idea, but he need also to change his computer name to the netbios name
of our samba (links are configured as \\serwer_name\share\something) to
make it work.
now when this computer connects to VPN samba seems to forget own name.
as i wrote - nmbd wins elections, employee's workstations are configured
to use samba's ip as wins, but they all just keep trying to connect to
.202 even if it's not connected anymore. the problem disapears when i
restart nmbd (i think so)

[ and then individual shares ]

It sounds like this computer's NMB entry is overwriting Samba's.  My
guess is the only way to stop this is to 'ban' this user from accessing
WINS and broadcasting NMB queries, so that they never reach nmbd and
can't overwrite the real server's entry.  This will mean however that
the user will be unable to to access the real Samba server over the VPN.

Alternatively you may find it better to map a network drive to the
macros - so instead of accessing files as \\server\share\macro you map
drive M: to \\server\share and then use M:\macro in the documents.  That
way your user can have M: pointing to a share on their local machine
(or even use 'subst' to make a local folder appear as drive M:) and
then at work have drive M: mapped to the server version.

That way you could have two different computer names and just change
the drive mapping to point to whichever version of the files you want.

Cheers,
Adam.
