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:
