Hi Chris,
While I have activated VPN and used it to connect to my work network
so that internal web servers were available via HTTP, I haven't tried
to access the file system on any server inside the firewall. I think
to do that you'd need to find some way to create a file pointer to the
C:\ drive and have software that will support navigating into it (eg:
Finder.app). But that would be a new thing to me. Have you tried
posting other places, like at
ipodtouchfans.com?
