I am new to creating WCF services. I have created a WCF web service in VS2008 that is running on IIS 7. When I use http the service works perfectly. When I configure the service for TCP and run I get the following error message.

There was a communication problem. The message could not be dispatched because the service at the endpoint address 'net:tcp://elec:9090/CoordinateIdTool_Tcp/IdToolService.svc is unavailable for the protocol of the address.

I have searched a lot of forums, including this one, for a resolution but nothing has worked. Everything appears to be set up correctly on IIS 7. WAS has been set up to run. The default web site has a net.tcp binding and the application has net.tcp under the enabled protocols.

I am including what I think is the important part of the web.config from the host project and also the app.config from the client project I am using to test the service. Hopefully someone can spot my error. Thanks in advance for any help or recommendations that anyone can provide.
