PPTP stopped working

[Harolds]

I have a VPN settup using PPTP, up until yestarday it worked just fine. Then
I started getting "Error 609: A device type was specified that does not
exist.", I noticed in Network Connection that my VPN connection shows "WAN
Miniport (L2TP)", I checked in properties under the Network tab and it is set
to PPTP VPN.

I tried setting up a new VPN connection but it did the same thing, showing
"WAN Miniport (L2TP)" though it is set to PPTP.

Can someone help me with this problem?

Found the answer which fixed the problem:

- open cmd

uninstall miniports

netcfg -u ms_l2tp
netcfg -u ms_pptp

install them again (order may not be important)
