I am running Windows 8.1 Pro.
On our older Windows 7 Pro pc, I can connect the VPN and then ping with no problem. On the new Windows 8 Pro pc, I can connect the VPN, and it returns: 'pinging servername [73.43...]' so it does show the IP, but then it shows: 'Request timed out.' Packets: Sent=4,Rec'd=0,Lost=4
I haven't used Telnet before, but I just read how to do it online and it returned 'Connect failed'.
Also, I do have a second website at a different hosting company. That site does not require a VPN and I can connect to that one from Windows 8, I just can't connect to our primary site above.
When I do 'ipconfig /all', the DNS Server seems to be exactly the same on both Windows 7 and Windows 8 pc's.
