Server 2022 RDS - Disconnected User reconnect to BlackScreen

Mark Lacey 26

Hello,

We are currently having an issue with an RDS 2022 Server.

Users log into a blackscreen after reconnecting to a disconnected session.

You are unable to log these users off without terminating LogonUI.exe, additionally if a user is idle on the blackscreen you can manually terminate LogonUI.exe and the users remote session will load up like normal.

Any support would be appreciated.

Thanks

I have built a number of RDS environments on RDS 2022 running on Hyper-v 2019.

I have this same issue where it always logs in fine but if the session goes idle and they return to it the get the black screen and you have to kill their processes and log them out and they log in and its ok again.

They also use FSlogix profile containers.

Importantly this happens about 1 in 20 times they return from an idle session and from a variety of clients, users and host servers. Logs show nothing unusual when it occurs.

I am having the same issues, brand new Server 2022 installation in VM-Ware with just basic settings. Not using FSLogix or any profile redirections.

The issue appears to be more frequent when I set an idle time limit in the RDP Gateway policies however even without setting any limits users are reporting issues when they try to reconnect a disconnected session.

Only fix when this happens is to kill the Windows logon user interface host process in task manager for the specific user. Sometimes even twice.

If I set an idle time limit I sometimes get the message "Please wait" when the the limit is reached. Nothing will happen you can wait for hours.

Also, when I have a RDP session open full screen it will usually stay on for quite some time without issues but if I minimize the RDP window within 5 minutes the session will crash into black screen or "Please wait" bluescreen.

These issues are causing a lot of headaches I have spent hours trying to troubleshoot this. Can't even find any usefull entries in the event log...

After spending another day trying to resolve this (even removing our managed services N-able and SentinelOne antivirus without any luck) I am now installing Server 2019 next to the 2022 server in the same domain to check if the issue is the same.

We have the exact same thing as Teun discribes, black screen hanging sessions, search and taskmanager are suspended. We can only kill the session by killing user interface host. It pops up randomly, we even had it on a FS with an admin account and no fslogix or other trickery. It seems to be a straight up windows 2022 bug as we are currently having this issue with 3 of our customers all on 2022. The sad this is that I have been searching for a solution for our customers for days, looking into all sorts of logs, trying all things. But I cannot find a trace or log why it happens. Tho I highly suspect the “app readiness” service to have something to do with it. Disabling it causes some

problems like start menu, search and outlook do not work properly. As for now, no patch seems to have fixed it and no reason or solution to be found :( if anyone has the key to solving this..

I am having this same issue for a new Windows Server 2022 Standard (10.0.20348 Build 20348) that has Remote Desktop Services configured. When a user reconnects to a disconnected RDP session they get a black screen that doesn't respond to anything. This happens even if I logon to a new RDP session, disconnect, and immediately try to reconnect. The only way to fix this session is to end the task for that user for "Windows Logon User Interface Host" and then they can get back in. I don't even have to sign off the user and if they are connected and looking at the blank screen when I end that task then it clears up while they are still connected. I confirmed that if they sign out properly this isn't an issue.

I have tried snoozing my Managed AV

I have tried removing N-Able Take Control

I have tried multiple users from multiple devices

Same issue here. The only thing is that I don't know which LogonUI.exe that's associated with which user? The LogonUI.exe runs as SYSTEM (and I have around 10 of them).How do I connect "Windows Logon User Interface Host" to a specific user?

I just wanted to add that since I reinstalled Server 2019 (after my last post Feb 4, 2023) I had zero issues with this server. So it is 100% a server 2022 issue. I see some posts that it is resolved after removing N-able but for me this was not the case. Shocking to see there are recent posts showing this has still not been fixed.

I am having the same issue. RDP to a remote pc via Remote desktop Gateway which is a 2019 datacenter server. When diconnecting/logoff from the remote machine, the RDP client goes to a black screen and will not disconnect or close. when checking the remote machine and the RDG server the sessions have been ended. so it appears that when the user logs off the remote machine the RD client doesnt disconnect properly and hangs with a black screen. Tried building a brand new server using 2019 datacenter but the same issue. Tried Remote Desktop client from multiple machines, same issue. RD Client on Win10, Win11, Server2016, Server2019 all the same. Tried multiple devices to RDP into as well.

Dear all,

After disabling the N-able Take control, the problem seems to be fully resolved on our side !

I am using N-Able Take Control so I am going to try switching that over to Team Viewer and see if that does the trick. I will post the results shortly.

I removed N-Able Take Control and the issue is still happening for me. If they user signs out properly then there is no issue, but reconnecting to a disconnected session still results in a black screen and having to end the task for that user for "Windows Logon User Interface Host" and the black screen goes away and they can continue.

Same error for me, two RDS 2022 with fslogix user container and no N-Able.

Ending Windows Logon User Interface Host works for me and the user can reconnect to the session without loosing data

Same problem here, Running VX_Rail, server 2022 standard VM's, only started after the last set of windows updates. Surprise Surprise... I kill the Windows Log-on application process and then it slowly kills everything except the Client Server Runtime process. I can then login the user with a bit of stuffing around and waiting from the clients PC. Last updates : KB5022842, KB5022735, Microsoft Edge Stable Channel (Version 110.0.1587.57). Happens to random users each day, no rhyme or reason.

Same problem here with fresh 2022 servers. Does anyone use some kind of 2FA software to login?

Im using Duo MFA, the same problem, random users, diffenrent clients (Win10, thin client,mac, win11), time. 50 users, sometimes 5 per day have the issue, sometimes a whole week without problems, occurs both when they disconnect and when they just using lockscreen, cant say that a newly rebooted server is better, 4 different RDS servers, 2022, fully patched. Worked fine with Windows 2016.

For me the problem occured with and without using DUO so I don't think it is related to that.

Hello All,

I had LogonUI.exe problems with my deployment of RDS server on Win2022. Basically if I've checked Even Viewer I could see errors where after user logged off and tried to reconnect then LogonUI would hang/crash. I've tested a lot of different options and tweaks, to no avail. Finally I started to take a closer look to LogonUI itself and found a correlation between LogonUI and transparency effects (User Desktop -> Personalize -> Colors).

When configuring transparency effects for the first time I turned them off for better remote desktop performance, as anyone usually does. What I've observed is when I turned them back on the LogonUI stopped hanging/crashing and functions depending on it started to work as they should once again. I had no errors in Event Viewer and users could login and logoff without any weird behawior.

You could give it a try - it's a 5 sec check, but maybe it will help you as well.

Best regards

Piotr
