XP下面默认只能同时打开两个VPN连接，在你打开第三个VPN连接的时候，就会找不到服务器，连接不上。这个时候，我们就需要更改一下XP里面的默认设置了：
1. Start - Run - regedit to open registry editor.
2. Locate \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Classes\{4D36E972-E325-11CE-BFC1-08002bE10318}
3. You can see 0000,0001… in the left tree. Just click one, and see the right side. On the right side, there is a item named “DriverDesc”. Find the proper one which “DriverDesc” is “WAN Miniport(PPTP)”.
4. And in the same page, we can see another item “WanEndpoints”. It default value is 2. We need to modify this to 5(Means we can connect 5 VPN connection at a time).
5. After modify this, close the registry editor and reboot the machine.
重启以后就OK了～
