Hi
I have searched all over the internet for an answer so hopefully someone here can help.
I have an SQL 2017 server set to use Windows or SQL authentication.
The DB's that are on it work fine using either authentication method on the LAN.
My issue is that when a user tries to connect over our VPN it will fail with the above error message about its login is from an untrusted domain.
However, if I use an SQL credential (SA) it connects no issues.
Both server and PC are on the same domain and the PC is regularly connected to the LAN during the day, its just when they go home and use the VPN that it doesn't work and I get this untrusted domain error. This happens for all users over VPN.
