Remote Desktop Gateway frequent disconnects after KB5040430

Anonymous

After installing KB5040430, we are seeing issues on the Server 2019 Remote Desktop Gateway on RDS.

All users get disconnected approximately every 30-60 minutes, and the following is logged in the Application log on the RD Gateway:

I have a Remote Desktop Gateway on a Windows Server 2022. Here the Windows service, Remote Desktop Gateway, kept crashing and users received the error code 0x300000d when trying to connect. Inspecting the event log on the server revealed this related error:
```
svchost (1976,R,98) SoftwareUsageMetrics-Api: An attempt to open the file "C:\Windows\system32\LogFiles\Sum\Api.chk" for read / write access failed with system error 5 (0x00000005): "Access is denied. ".  
```
Granting Modify access to the NETWORK SERVICE on the folder C:\Windows\system32\LogFiles\Sum resolved the issue. The RDG service now runs without crashing unexpectedly.

So it's September 25 and still no fix for this issue from Microsoft?

Would you be so kind and let us know if you have received an “out of band” update from support in the meantime. Unfortunately, I couldn't get any information from Microsoft with a case.

I was trying to get this Rollback.msi from this thread:

Patch Tuesday Megathread (2024-07-09) : r/sysadmin (reddit.com)

I wanted to get up to date information before trying it especially as this was from July. I am waiting a callback for confirmation but I got the impression I knew more about the issue than the tech that called me... :(

I can confirm that the KIR from the Reddit article works on Server 2019 with the latest September CU. I was about to remove the KIR, but then found the known issue was not resolved in September's patch so I have left the KIR on.
