Always On VPN is functional except on one user's machine so far.
The user's machine was added to the domain, they got a valid certificate for authentication to connect via the Cert. Auth.
We utilized the users network account, not local account
I added all the VPN items, in, like every other machine (and it works on every other one)
When I hit connect on that machine it starts to connect to the VPN, but then prompts for user/pass credentials. No other machine has prompted for these. I have tried the users local/network profiles
I have tried domain/local admin profiles
Nothing works at all
Every other machine can connect, 0 issues minus that one. They are all domain joined, domain accounts, same certificates.
Ideas before I throw it out a window?
