Suppose I have a laptop joined to a Windows 2000 AD domain. Suppose then
I shut off the laptop and take it home. Then I boot back up and logon as
a cached domain user. Then I plug it into my Internet connection. Would
it be possible to access a file server on my domain through the Internet
and automatically log on to it as the cached domain user without a
password prompt, like it would if the laptop was connected to the local
network? Or is this only possible if you use a VPN to the local network?
Please ignore the fact that what I am asking would be a bad idea security
wise - I just want to know if its possible and how to make it work.
Thanks for any help,
Josh
