SYMPTOMS

When you try to connect to an instance of the Remote Debugging Monitor in Microsoft Visual Studio 2005, you may receive an error message that resembles the following:
Unable to connect to the Microsoft Visual Studio Remote Debugging Monitor named MonitorName. The Visual Studio debugger cannot connect to the remote computer. An RPC policy is enabled on the local computer that prevents remote debugging. Please see Help for assistance.
When you click Help, you obtain a document that states that you need to disable the Restrictions for Unauthenticated RPC clients policy setting. However, the problem is not resolved when you disable this policy setting.
