Microsoft's July 2024 cumulative updates for multiple Windows Server releases (including KB5040437, KB5040430, KB5040434, KB5040456, KB5040485) introduced a known issue that can cause the Remote Desktop Gateway service to crash every ~30 minutes and interrupt RDP sessions when legacy Remote Procedure Call over HTTP is used; Microsoft documents symptoms (TSGateway termination, 0xc0000005, Event 1000) and provides two temporary mitigations—blocking \pipe\RpcProxy\3388 via firewall or setting HKCU\Software\Microsoft\Terminal Server Client\RDGClientTransport (DWORD) to 0x0—while advising registry backup prior to changes.
