This was really annoying. After installing SP2 I could not connect to the several VPN sites I need. After contacting Microsoft here is the resolution they provided that worked. I’m posting here to save others the trouble I went through.
First turn on RAS logging to diagnose the problem. You’ll need to open an administrative shell (cmd) to run these commands.
create a trace:
netsh ras set tracing * enabled
try your VPN connection (i.e. failure)
netsh ras set tracing * disabled
Look in your \windows\tracing folder for RASGCW.LOG
If you see a string like:
ConnectThread:RasDialDlg failed with error: 800
This should fix your problem. You’ll need to reinstall some drivers.
first uninstall:
netcfg -u ms_l2tp
netcfg -u ms_pptp
then re-install:
netcfg -l %windir%\inf\netrast.inf -c p -i ms_pptp
netcfg -l %windir%\inf\netrast.inf -c p -i ms_l2tp
That’s it. Let me know if you had this problem as I am curious.
