Hello everyone,

My problem happens on windows 8 release preview. When I am try to connect through a VPN using WiFi network or LAN, I getting the Error 850 '' The Extensible Authentication Protocol type required for authentication of the remote access connection is not installed on your computer".

Do you have any fix for it?

Since it sounds like you are early in the testing of Win 8 RP, perhaps this article from Wiki (http://www.wiki-errors.com/err.php?wiki=850)will help. If not, perhaps a reinstallation using a new download and new slow burned DVD will solve your problem. According to all I've read about this error code this is a system file problem.

I am having the same problem. Any ides or fixes?

Edit the properties of the VPN account and select the Security Tab. Change Data encryption to Optional. Also check "Allow these protocols". It is highly likely you are using MSCHAPv2 so select that and see if you can connect.

Good its works.
