[Samba] Can see folders but not files connecting through VPN

[Rohan Tanner]

We are having an issue with our Windows Xp laptops on our network when
connecting in using a VPN. When connected directly to the LAN this
problem does not occur

When a user connects to our network through a VPN (using secure ID
tokens)they are able to browse to their home directories sitting on a
redhat box running Samba 2.2.5-1. They are able to see all the
directories but not any files contained within.

As soon as they return to the office and plug into the LAN they are able to
see all the files again.

Any ideas would be appreciated

Cheers
