I have a Windows 2003 Server and I deployed the service to that server such that the reference is now 10.10.90.1 instead of localhost. I also chnaged the clientBaseAddress to http://10.10.90.1:8000/StockService/ and I am still getting the same error - any ideas?
BTW - THe WSDL looks fine and I can obtain it without any problems through a browser.

I am just now delving into WCF and I am trying to reolve the latter error you described for IIS 5.1 running on XP. I have attempted to emulate your solution but I still get the same error - below is my configuration file - can you please help? Thanks!

This is great, but how do I detect the client’s machine name from .NET? And there is one more thing: if I specify a clientBaseAddress and run more than one instances of the client application, it will also throw this exception, because the other instance of the client already uses that particular port.

when You say that we have to “use resolvable address (i.e. your client machine name for example)”
You mean that client computer has to be ‘visible’ from server?

by ‘visible’ I mean that you can ping client computer from server by it’s name

in my app.config I have clientBaseAddress=”http://client_machine_name:8000/myClient/”
but I still get timeouts…

please help…

Darshan, you can share port 80 with IIS if you are using 2k3 server or later (that is, IIS 6.0 and later). IIS 5.1 (on XP) does not use http.sys and there for you cannot share port 80 with IIS on XP.

Sunil, it sounds like an application already has 1045 open. You can use “netstat -a” to see which process has 1045 in LISTENING mode.

Really good help Kenny but i have one problem I have override ClientBaseAddress property on WsDualHttpBinding like clientBaseAddress="http://localhost:1045/WCFTest.Host/"> Now it gives me this error: HTTP could not register URL http:// :1045/WCFTest.Host/ because TCP port 1045 is being used by another application what should i do? please help me. ***********This is my configuration code **************************

Does this mean that i could have a self hosted WCF service share port 80 with IIS? If so, how do i go about sharing the port?

Thanks Kenny - that helped out greatly.

A couple of additional notes, related to my experience.

1) I found that, if the service is already using a non-standard port, the client should use a different non-standard port (e.g. Service uses port 666, Client uses port 667). This may be obvious to some.

2) Anti Virus programs may complain if non-standard ports are used. Mine did, so I had to add the two applications to the permitted list of executable files.
