The problem occur when client and server don't agree upon
a common host name, for example when the server has a
hostname w/out a valid DNS entry.

Try to find out the URI by calling RemotingServices.GetObjectUri()
on the returned object. Does it return something that your client
is able to connect to? If not, your server is probably missconfigured.

You may also try to apply some remoting config settings
in the app.config of your server, especially "bindTo" and
"machineName". See
