I have a small network with a dozen computers all connecting remotely over PPTP VPN fed by a 2003 server. Three are Windows 8 machines and the rest are Windows 7 and Mac OSX.
All of them can connect and stay connected to the VPN with the exception of one system. It connects to the VPN, but then disconnects at 1.75 minutes later like clockwork.
1. It was connecting fine, but stopped about two weeks ago.
2. No Windows updates correspond to the stop.
3. Antivirus has been uninstalled.
4. Firewall has been disabled.
5. VPN has been deleted and recreated multiple times against known good Win 8 VPN settings.
6. Logging on client side simply shows "connection disconnected". No error. Event 20268.
7. Logging on server side shows Event ID 20194 "disconnected by user".
8. Have tried wireless and wired connection.
9. Have tried and entirely different network at another location and issue followed computer.
Any further help would be greatly appreciated.
