Is there a way to reset to factory defaults the files and settings for Window's L2TP / IPSec with Certificate without reinstalling the OS? I get these generic errors: Error 789 in event viewer or "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer"

I have tried disabling XBOX services, and I do not have any problem connecting with other windows 10 computers on the same network. In fact the connection used to to work for me in prior versions of Windows 10 until XBOX started to rear its head. I just don't know how to get that functionality back without a fresh install of the OS.

Any suggestions, or thoughts?
