Is it possible that you have disabled Routing and Remote access and enabled
the Windows Firewall. This would fit your description of your problem
exactly. You must disable the Windows Firewall on the advanced tab of your
connection properties. Then, re-enable routing and remote access by clicking
Start --> Administrative Tools --> Routing and Remote access. Both of these
services cannot run together. You must disable the ICF first b4 proceeding.
If this is not your problem then it was a shot in the dark....
