Hi Kenny

on your last comment you say “if you want to use port 80 on XPSP2 then you need to disable IIS or change the port that it’s using.” i am very low on knowledge about ports and IIS etc.

Can you explain this in dummy form. I cant disable IIS as i need it for other things, so do i change the port IIS is running on or the port that the service runs on and if the latter how do i do this (I have tried the former but it doesnt appear to make any difference) ?

cheers
Karyn

Godwin, if you want to use port 80 on XPSP2 then you need to disable IIS or change the port that it’s using.

echoe, let me provide some counterpoint here.
1) NetTcpBinding is intended to be used within a corporation/network (i.e. intranet). For most internet-based communication you need to use HTTP as that’s what’s widely deployed and supported through proxies, etc. NetTcp was never intended to replace all uses of TCP
2) WsHttpDualBinding was intended for scenarios where both sides are globally addressable (such as B2B communication). It was not intended to address NAT traversal.

For what you are desiring (i.e. bidrectional communication behind a NAT/firewall), you’ll want something like the HTTP polling duplex channel that’s shipped in Silverlight. It uses a client-based HTTP polling mechanism to allow bidirectional communication to occur even though it’s always “initiated” by the client from the HTTP perspective.

Santhosh, it sounds like you need to setup proxy authentication on your binding.

Venemo, Environment.MachineName will help you out. Peter, I wonder if you need to add a firewall exception.

You can use the same port number as long as the base URI paths are distinct.

If I have more than one client, will I have to come up with a different port number for each client?

Sir I have a windows application running which starts WCF service. Another windows application has to interact with the WCF service. Now my error is

The remote server returned an unexpected response: (407) Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )

In local system it works fine but in remote application it is not working.

Please help me in this problem.
