Hi,
since a few days, we have issues while trying to connect from Windows 7 & 10 clients to a Windows Server 2012R2 RD Farm.
RD farm is composed of two RD session hosts + 1 RD Gateway.
Windows 10 clients are build 1809.
The clients and the servers are in different domains with one-way trust. It worked just fine until a few days ago, when clients started getting the below error message. In the TerminalServices-Gateway/Operational log file, I can find a lot of 312 and 313 events which indicate that connections are not authorized.
I have no clue what changed as compared to when the connections where working fine.
We introduced the Microsoft Remote Desktop app as a workaround, and strange enough that works, but it is not liked very much by our users cos it has some drawbacks.
Can anyone help me, or point me where to look at?
Thanks,
