Windows Server-based VPN/RRAS does not receive domain credentials for file sharing

Salvation,

I’m a school’s sysadmin and since the January 2022 VPN updates + patches, all users running up-to-date versions of Windows 10 (couldn’t test on 11) can connect to the VPN/RRAS server but cannot access network resources. UseRasCredentials is still enabled, so that’s not the problem.

I recreated the connection as well as the server configuration. I even created a new server using a fresh install of Server 2022 to see if it works (main server works in 2019). I’ve been using a machine that hasn’t been updated recently tonight and was able to map drives with no problem, then apply updates, then lost the ability to do so.

From what I can understand, usually credentials are entered into the credential manager so that those credentials are used for file sharing and SQL queries, but without that, l local user is used, which obviously has no permissions on the network, so you get an incorrect password message.

I can’t find much about it online other than one person on the Microsoft Tech Community forum (https://techcommunity.microsoft.com/t5/windows-servicing/january-2022-quality-update-breaks-passing-domain-credentials/mp/3072773). They suggested a workaround, but it won’t work for my users because their passwords are updated regularly and also need me to do everything for them, and that’s exactly what a workaround is.

Does anyone have any idea why this is happening or what I could do to investigate the cause?

Thank you,

Paul
