I have Windows 7 Ultimate and when I am trying to set up a VPN connection a requirement is to make an adjustment in the Protected EAP Properties window to uncheck the Validate server certificate and to check the Enforce Network Access Protection boxes. When I do this then 'ok' the change in that window and 'ok' the changes to the Security Tab seting in the VPN setup it does not save the change I made. I go back in to the same Security tab in the VPN window then into the Properties of the Microsoft: Protected EAP (PEAP) (encryption enabled) Authentication and the changes I had just made are not there. Why will this not work? Is there a way to correct this so that it will save?

I'm having the same issue. did u get a resolution?

I'm having the same issue. Any resolution?

I'm having the exact same issue. Did you get a resolution? Thanks.

Did y'all all have Cisco PEAP as one of the authentication choice?

In my case this problem was presents only in Lenovo laptops, and the solution is use the Lenovo Access Connection Program, for configure VPN properties. Create new profile, on Aditionals values Enable VPN connection, on values add VPN created previously (on Control Panel, network and internet), select Edit, go to Security option and Use EAP (PEAP) properties, write server name, certificates, enable Network Address Protection and select OK two times. Check again VPN parameters on Control Panel, Network & Internet, Network connections, VPN configuration, Security. I hope this can help you Best Regards.Donato
