I have a networked drive on the XP side of my MacBook. I use a VPN and then can login to the drive. Nothing too special going on. I believe the server uses Active Directory.
There isn't a ton of info I have to enter. The \\server.local.blah
blah
and some IP info.
I have never been able to get these to mount or show up and authenticate on the Mac side. I can use the network connect to login to the VPN, but directory access has always been a no-go.
