The Visual Studio debugger cannot connect to the remote computer. An RPC policy is enabled on the local computer which prevents remote debugging.

To correct this error

  1. Run \windir\system32\regedt32.exe

  2. Locate and delete HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\RPC\RestrictRemoteClients.

  3. Restart your computer so the registry change will take effect.

  4. If the problem persists, contact your domain administrator about the Computer Configuration > Administrative Templates > System > Remote Procedure Call > Restrictions for Unauthenticated RPC clients group policy setting.
