I'm hoping someone on Daniweb may be able to help me out with this problem I'm having:-
Since Thursday, people have not been able to access their work computers from home over a VPN connection. Users can authenticate through the firewall and register on the network (the server gives them an IP address) but when they try to access their PCs with remote desktop in XP or Vista, they cannot.
I was able to test this out yesterday evening and found that I could get through the firewall with no problem, but as described, could not access my computer - in fact, I could not even ping it. The only computer I could ping was the server (running Windows SBS 2003). Even at that, I could not use remote desktop - it just came up as a black screen.
Nothing to my knowledge has changed on the server and I have certainly not changed any settings. One interesting note is that a colleague was able to ping someone else's PC. I don't know why it should be different to any other machine, he able to do so but got the same problems I had with remote desktop - a black screen. Every other PC he tried he could not ping. I do not think he tried the server.
If anyone's ever heard of anything like this or has any suggestions it would be greatly appreciated. :)
Thanks for your time,
