Any fixes?

Answer 1

Hi,
Several steps you could have a try:
1.Go to Microsoft Remote Desktop > preferences > General Tab> uncheck “use system proxy configurations “ and
Also uncheck “Use hardware acceleration ”

This is one suggestion shared in another thread and many users reported that if fixed their issues.

I'm also having RDP issues after Big Sur update. My issues is after connecting, the window rapidly "flickers" I'm running OS X 11.0.1 and RDP client 10.4.1. Turning off hardware acceleration doesn't work.

Answer 3

I'm having the same issue. I tried the recommendations mentioned above but they didn't work for me. I have Microsoft remote desktop 10.5.0 version and Big Sur as well. How can I make it work again? I tried calling Microsoft but unable to speak with a real person.

Error code: 0x204

I am able to connect from a different Mac that doesn't have the Big Sur update, so evidently the remote computer is ok. The problem is the upgrade.

Help!

turning off gateway and graphics acceleration fixed my issue of user account but now I get an error about password being old? I also tried the newest version on Catalina and that gave the same issues.
Connecting to a windows server via VPN - can ping server, just cannot get it to connect

Answer 5

For me, Remote Desktop worked under both Catalina and Big Sur until we removed NTLM authentication to force Kerberos only. Once this was done, Domain\Users could no longer log into remote computers. The only account that does work is the Domain\Admins account. Administrators can log into remote machines as Administrator but they cannot log in as any other user.

In my case, it would appear to be an authentication issue when Active Directory is not using NTLM.

We have tried the latest Beta build 10.5.1 and it has the same issue.
