Admins can monitor this as a TSGateway service termination subject, which triggers an 0xc0000005 exception code When it turns into unresponsive and will get logged as Occasion 1000 within the system occasion log.
“Windows Servers might affect Remote Desktop Connectivity across an organization if legacy protocol (Remote Procedure Call over HTTP) is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted,” Microsoft stated on the time.
“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.”
