Remote Apps (Work Resources) authentication error

Question

Remote Apps (Work Resources) authentication error

Chamong Lo 0

Hello,

We have a 2019 windows server that is acting as a Remote Desktop Server. Remote Apps (Work resources) works fine on windows 10 devices on an internal and external network, however, on a windows 11 device it will only work properly on the internal network. If i were to use Remote Desktop Connection to directly connect to the RDS it will connect just fine, but when I use our Remote Apps the error i am getting is "An authentication error has occurred. The token supplied to the function is invalid. Remote Computer: ......."

We are using Direct Access to connect to the internal network.

Please let me know if you have any ideas how to fix this.

Any updates on this? I have started seeing the same issue with some Windows 11 devices and I am out of work arounds to try and get this to work. Same scenario as described in post. Seems to be the same issue with Win11 22H2 that was "fixed" in a January update. These problem PC's are all up to date with windows updates and a few are straight out of the box.

Unfortunately no there is no update. I still get the same issues. When the user works remotely i just decided to have them remote into the RDS directly or if you still have the chance to, downgrade back to windows 10.

Unfortunately no, there has not been any update. My only workarounds were to have the remote user on an external network to RDP straight into the RDS itself or if you can still downgrade to windows 10, i'd recommend that.

I am having the same issue and the only thing I have found is the below Microsoft documentation. I have not tried it yet though.
If you try it let me know if it works.

Hello there,

Have you made any recent updates on the device? If so try to uninstall them as there are history of updates creating this issue.

Try the below steps and see if that helps if you have not made any recent updates.

Click 'Start' > 'Accessories' > 'Remote Desktop Connection'

Click the 'General tab', and check the box called 'Always Ask for Credentials'.

Click 'Save'.

If NLA is enabled on your RDP server, this means that CredSSP is used for RDP users’ pre-authentication. You can disable Network Level Authentication in the System Properties on the Remote tab by unchecking the options “Allow connection only from computers running Remote Desktop with Network Level Authentication (recommended)”

Hope this resolves your Query !!

Yes, unfortunately i have tried those options already and no luck either. Only recent update i did was upgrade from windows 10 to 11 to test if windows 11 was the issue in this case and it was. Like i stated before, this only seems to be occurring on a Windows 11 device connected to an external network while working remotely.

I was able to test and looks like windows 11 21h2 has no issues but windows 11 22h2 does

My environment consists of multiple 2016 RDS servers behind an Azure load balancer. After working with the issue, I was able to determine that the authentication error listed above was only happening when the incoming connections were routed to the RDS server that also serves as the connection broker. My work around for this is to only direct incoming traffic to the RDS server that is NOT also the broker (not running broker in HA). If a Window 11 22H2 hits the RDS with the connection broker first, fails with that authentication error. Has to come in to the non broker server first and then works as it should.
