KB5041578 Hotfix Available yet?

Question

KB5041578 has caused a number of our servers to become unresponsive.

I have read through the blogs and the reddit pages, and they provide a fix - but it's not easy.

When will Microsoft release a hotfix for this issue?

Answer 1

Hello,

Thank you for posting in Microsoft Community forum.

Based on the description, I understand your question is related to KB5041578.

Yes, after installing the Windows update released on or after July 9, 2024, Windows Servers might affect Remote Desktop Connectivity across an organization. This issue might occur if legacy protocol (Remote Procedure Call over HTTP) is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted.

This issue might occur intermittently, such as repeating every 30 minutes. At this interval, logon sessions are lost and users will need to reconnect to the server. IT administrators can track this as a termination of the TSGateway service which becomes unresponsive with exception code 0xc0000005.

To work around this issue, use one of the following options:

Option 1: Disallow connections over pipe, and port \pipe\RpcProxy\3388 through the RD Gateway.

This process will require the use of connection applications, such as firewall software. Consult the documentation for your connection and firewall software for guidance on disallowing and porting connections.

Option 2: Edit the registry of client devices and set the value of RDGClientTransport to 0x00000000 (0)

In Windows Registry Editor, navigate to the following registry location:

HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client

Find RDGClientTransport and set its value to 0 (zero). This changes the value of RDGClientTransport to 0x00000000 (0).

Microsoft is working on a resolution and will provide an update in an upcoming release.

Have a nice day.

We read this issue was addressed in KB5043050 here:

https://devicebase.net/en/microsoft-windows-server-2019/updates/kb5043050-addressing-remote-desktop-known-issue-and-other-bug-fixes/4yw

The official site: https://support.microsoft.com/en-us/topic/september-10-2024-kb5043050-os-build-17763-6293-66e9809a-1838-4474-a6a7-90d64f042f00 States that the KB resolves [Windows Server 2019 (known issue)] yet also states to implement workaround in Known Issues. I do not trust that KB5043050 addresses the issue. We will wait to deploy this update due to the huge impact this known issue has on our environment disconnecting users after over 30 RDP connections through the server farm.
