I have a WCF service and a Windows client. They communicate via a Duplex WCF channel which when I run from within a single network domain runs fine, but when I put the server on a separate network domain I get the following message in the WCF server trace...

The message with to

'net.tcp://abc:8731/ActiveAreaService/mex/mex' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree.

So, it looks like the communication just work in one direction (from client to server) if the components are in two separate domains.

The Network domains are fully trusted, so I'm a little confused as to what else could cause this?

Server app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
    	<behaviors>
    		<serviceBehaviors>
    			<behavior name="JobController.ActiveAreaBehavior">
    				<serviceMetadata httpGetEnabled="false" />
    				<serviceDebug includeExceptionDetailInFaults="true" />
    			</behavior>
    		</serviceBehaviors>
    	</behaviors>
    	<services>
    		<service behaviorConfiguration="JobController.ActiveAreaBehavior"
    				 name="JobController.ActiveAreaServer">
    			<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""	contract="IMetadataExchange" />
    			<host>
    				<baseAddresses>
    					<add baseAddress="net.tcp://SERVER:8731/ActiveAreaService/" />
    				</baseAddresses>
    			</host>
    		</service>
    	</services>
    </system.serviceModel>

</configuration>

but I also add an end point programmatically in Visual C++

host = gcnew ServiceHost(ActiveAreaServer::typeid);

NetTcpBinding^ binding = gcnew NetTcpBinding();
binding->MaxBufferSize = Int32::MaxValue;
binding->MaxReceivedMessageSize = Int32::MaxValue;
binding->ReceiveTimeout = TimeSpan::MaxValue;

binding->Security->Mode = SecurityMode::Transport;
binding->Security->Transport->ClientCredentialType = TcpClientCredentialType::Windows;

ServiceEndpoint^ ep = host->AddServiceEndpoint(IActiveAreaServer::typeid, binding, String::Empty); // Use the base address

Client app.config

    			</identity>
            </endpoint>

Any help is appreciated!
