Windows Remote assistance does not work after installing KB5050008

Question

Hi

Windows 2019 RDS Hosts

After installing KB5050008 we have found we could not initiate and connect via windows remote assistance

the typical "Your offer to help could not be sent" , check permissions, is it turned on, is there a network problem error message

the event log from the host that tries to initiate the session

"There was a problem interacting with COM object 833E4010-AFF7-4AC3-AAC2-9F24C1457BCE. An outdated version might be installed, or the component might not be installed at all."

Once KB5050008 was removed we could successfully connect with remote assistance

anyone else come across this?

Thanks

Hello,

KB5050008 Updates may not be compatible with certain components or configurations in the system, causing Remote Assistance to not work properly. The COM object interaction failure mentioned in the event log may be due to some system component not being updated or registered correctly.

1. Repair or re-register the COM component. Open the Command Prompt (cmd) with administrator privileges and run the following command to re-register the relevant COM component:

regsvr32 /u msrdp.ocx

regsvr32 msrdp.ocx

Restart the server to apply the changes.

2. Make sure that the network settings for Remote Assistance and Remote Desktop Services are correct and that the firewall is not blocking the relevant port (e.g. 3389). Check the user's permissions to make sure they have permission to log in remotely.
3. Make sure that the system has installed all the necessary updates, especially those related to Remote Desktop Services. If an KB5050008 update is causing problems, you can try uninstalling the update and then reinstalling it to make sure the update process completes correctly.

4.Open the Event Viewer and navigate to: Applications and Services Logs>Microsoft>Windows>RemoteDesktopServices-RdpCoreTS and TerminalServices-LocalSessionManager, check whether the error message is reported at the point in time when the problem occurred.

5. Open the Group Policy Editor (gpedit.msc) on the target server, navigate to: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Security，disable“Require user authentication for remote connections by using Network Level Authentication”, then enable“Require use of specific layer for remote(RDP) connections”，And change the security layer to the RDP security layer.

Open cmd with administrator privileges, run gpupdate /force to make the modification take effect, restart the server, and then try to connect remotely to see if the problem can be reproduced.

I hope this information helps.

Best regards,

Thanks, but none of those options helped.

Same issue occurs on Windows 2016 RDS hosts.
