We created an AD account for an outside vendor to remote to a server. We set up the Logon to limitation to only allow the account to log into the server not other domain computers.
The vendor uses his own computers which is non domain computer to log into our VPN first and then remote to the server with our domain name in front of his user name, but he got the error message like the image below. Where did I miss and how to fix it? Need help!
