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 ClientFindRDGClientTransportand set its value to0(zero). This changes the value ofRDGClientTransportto0x00000000 (0).We are working on a resolution and will provide an update in an upcoming release. |
For the current status of any past known issue, see the Windows Server 2012 Known Issues page. |
