I had a problem connecting to my companies VPN a while ago.  I found running the following helpful:

Uninstall PPTP & L2TP Protocols:

Windows PowerShell

PS C:\Windows\System32> netcfg -u MS_PPTP
Trying to uninstall MS_PPTP ...

...done.

PS C:\Windows\System32> netcfg -u MS_L2TP
Trying to uninstall MS_L2TP ...

...done.

Re-install PPTP & L2TP Protocols:

PS C:\Windows\System32> netcfg -l c:\Windows\inf
etrast.inf -c p -i MS_PPTP
Trying to install MS_PPTP ...

...c:\Windows\inf
etrast.inf was copied to C:\Windows\INF\oem69.inf.

...done.

PS C:\Windows\System32> netcfg -l c:\Windows\inf
etrast.inf -c p -i MS_L2TP
Trying to install MS_L2TP ...

...c:\Windows\inf
etrast.inf was copied to C:\Windows\INF\oem69.inf.

...done.
