Error: Remote Debugger Service is Unable to Connect to This Computer

When trying to do remote debugging, you may get the following error message:

Error: The Visual Studio 2005 Remote Debugger service is unable to connect to this computer.

This error means that the Visual Studio Remote Debugger service is running under a user account that does not have permission to connect to the computer you are debugging from (the host computer running Visual Studio).

The following table shows what accounts can access the computer:

LocalSystem account

Domain account

Local accounts with the same username and password on both computers

Both computers on the same domain




Both computers on domains with two-way trust




One or both computers on a workgroup




Computers on different domains




In addition:

  • The account you run the Visual Studio Remote Debugger service under should be an administrator on the remote computer so that it can debug any process.

  • The account also needs to be granted the Log on as a service privilege on the remote computer using the Local Security Policy administrative tool.

  • If you are using a local account access the computer, you need to run the Visual Studio Remote Debugger service under a local account.

To correct this error

  1. Make sure the Visual Studio Remote Debugger service is properly set up on the remote computer. (See How to: Set Up Remote Debugging.)

  2. Run the remote debugger service under an account that has the proper permissions, as shown in the table above.
