I've used Remote Desktop on Mac regularly to connect to a domain-joined Win11 machine in my house. Just recently, it's stopped working. This happened on two macs, and it had the same suspicious start.
I tried to connect normally. Then, in the middle of setting up the connection, I killed the connection for some reason. Then, when attempting to connect again, RD always produces one of two errors:
1. It sits on the 'configuring remote PC' dialog for a while, then eventually fails with error code 0x204.
2. It actually succeeds in connecting, but it opens up a black screen. The desktop never loads, and the connection eventually fails with error code 0x10b.
Notably, I only see this issue with the one domain-joined Win11 machine. A separate Win10 machine I have doesn't exhibit this behavior.
