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


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, the 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 someone on the Microsoft Tech Community forum ( -passing-domain-identifiers/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,
