Hello,
I have been having an issue with VPN connections on some windows 10 Machines, this does not happen on windows 7 and while not all Windows 10 Machines are affected it seems this is the only common factor.
The issue is as follows:
VPN is setup initially either from "Settings" or "Control Panel".
User credentials and VPN settings are entered in the Settings menu
After then going to control panel and changing the protocol to "PAP", the user authentication changes to "General Authentication" which would remove their credentials.
If you setup the PAP protocol first via. control panel, then enter the user credentials under the "Settings" menu, the PAP option (Use following Protocol) will be unselected. I have set up VPN connections multiple time within Windows 10, but have need seen anything like this. Any and all help would be appreciated.
