Remote Debugging msvsmon is running in ‘Windows Authentication’ mode

Solved1.49K views24th November 2022DIS INJECT msvsmon remote debugging

When trying to remote debug, I can connect to the msvsmon service on the remote machine, but for some reason the connection request is rejected by the remote debugger.

The error I get is:

2021/07/27 09:21:47.144|Could not retrieve processes:

System.Runtime.InteropServices.COMException (0x8004076B): Connection request was rejected by the remote debugger. Ensure that the remote debugger is running in ‘Windows Authentication’ mode.

at EnvDTE100.Debugger5.GetProcesses(Transport pTransport, String TransportQualifier)

at Skyline.VSX.ProtocolEditor.Toolwindows.ViewModel.QActionDllManager.AttachToSLScripting()

I have made sure to run both visual studio 2019 as Administrator on my local machine and the msvsmon.exe as administrator on the remote machine. I have also ensured that under Tools of the remote debugging service Windows Authentication mode is selected and given permissions to the “Everyone” under the Group or user names section, see screenshots attached.

Does anyone have any idea what I’m missing here?

Thank you,

Ryan

Could you please try to connect to the remote debugger via Visual Studio itself instead of DIS? That can be done via Debug > Attach to Process, and following the instructions that can be found here. Maybe that will provide you a more detailed error message and explanation of how to solve it.

Everything seems to be configured correctly. So the only thing I can come up with is that the Visual Studio can find the Remote debugger, but the remote debugger somehow fails to authenticate the user.

If there is a firewall between the remote server and the visual studio machine then it could be worthwhile to check if all the ports are configured as described in the microsoft help
