Hello I am hosting remoting within IIS. Everything works just fine as long as I allow anonymous access at the IIS level. When I allow only Windows Authenticated sessions, something very strange happens: If the client activates the remote object with IP address - works fine If the client activates it using a machine name - get http 401 exception is thrown. The exception is thrown when the client calls the remote method. I set the channel's useDefaultCredentials property to true. Any idea how to allow Windows Authentication? Here is the call stack: System.Net.WebException: The remote server returned an error: (401) Unauthorized .. ---> System.ComponentModel.Win32Exception: The target principal name is incorrect at System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean handshakeComplete) at System.Net.NTAuthentication.GetOutgoingBlob(String incomingBlob, Boolean handshakeComplete) at System.Net.NegotiateClient.DoAuthenticate(String challenge, WebRequest webRequest, ICredentials credentials, Boolean preAuthenticate) at System.Net.NegotiateClient.DoAuthenticate(String challenge, WebRequest webRequest, ICredentials credentials, Boolean preAuthenticate) at System.Net.NegotiateClient.Authenticate(String challenge, WebRequest webRequest, ICredentials credentials) at System.Net.AuthenticationManager.Authenticate(String challenge, WebRequest request, ICredentials credentials) at System.Net.AuthenticationState.AttemptAuthenticate (HttpWebRequest httpWebRequest, ICredentials authInfo) --- End of inner exception stack trace ---
