1. What is the Remote Debugger? The Visual Studio Remote Debugging Monitor ( msvsmon.exe ) is a small application you deploy on a machine without Visual Studio installed. It allows a full Visual Studio 2022 instance on your development machine to attach to processes running on that remote machine (physical, VM, IoT device, or container) and debug them as if they were local.

Restart msvsmon.exe , run it as administrator, disable authentication temporarily, and re-enable Windows Authentication step by step until you find the culprit (usually firewall or permissions).
