For the last 2 years both computers had Windows XP installed. Desktop was connected to the internet via VPN connection to the ADSL modem, and Laptop shared that VPN connection via ethernet.
Now I decided to install windows Vista on the desktop. I can connect to the internet just fine, using the VPN CONNECTION (Wan Miniport PPTP), specifying the IP of my ADSL modem (10.0.0.138).
I believe the network between the Desktop and Laptop is working, as they see each other in the workgroup, and can PING each other. When playing the game WARCRAFT 3 over LAN, the computers cannot join each other, but that is not the issue right now.
I set the VPN Connection on vista to share with other computers. On the laptop, the icon with the VPN connection pops out in network control panel, signifying that the connection is shared (just like it was in XP, just with a different description). However -- there is no connection, as I can't access webpages on the laptop.
I hope someone will know how to help me, I am willing to cooperate and further describe the problem.
Vista isn't all that good at the moment with networks which include XP systems and printer sharing. Could have a look at the future release notes of SP1 for vista and see if your problem will be resolved with that.
Are you on the home edition or Pro - there are more functions on the Remote Desktop with the Pro version - the home edition can only be a client - if you want the Vista machine to be the server you will need the Business or Pro version
