Unable to Connect to the Microsoft Visual Studio Remote Debugging Monitor
This error message appears when you enter an invalid Visual Studio Remote Debugging Monitor name in the Attach to Process dialog box. The Remote Debugging Monitor name is usually the same as the machine you are attempting to connect to for remote debugging. This message may occur because the remote machine does not exist on the network, the remote debugging monitor is not properly set up on the remote machine, or the remote machine is inaccessible due to network problems or the presence of a firewall.
To correct this error
Make sure the Visual Studio Remote Debugging Monitor is installed and running on the remote machine.
Make sure the Remote Server Name is correct in the Name box in the Project Properties dialog box.
Verify that the remote machine is accessible on the network.
