Why can I only make a maximum of 2 VPN connections concurrently from my Windows XP client?
Posted on 2006-05-17
I support a number of customers and use a Windows XP client to make a VPN connection to their networks. I have tried from a number of different client machines from inside a company network and also using a direct connection to the Internet, but I find that in all cases, I can only make two VPN connections at any one time. If I try to connect a 3rd, I get "Error 800: Unable to establish the VPN connection". I can connect to any 2 of the 4 customer networks that I regularly visit, but never to more than two at a time.
The VPN server at each customer site is either Windows 2000 server or 2003 server. I have access to each of them, so can make changes to the server configurations or on my Windows XP client.
I have mentioned this to several people, and also searched to see if anyone else has encountered this problem, but without any luck.
