WCF communication blocked by firewall (or something)

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :WCF
So here's the deal... I have a web application with WCF services hosted in the web while the client is a WinForm app. Even though the web app listens on both port 80 and 443, some clients (PC clients) can't reach the services getting a TimeoutException.  In some cases I figured out the was a local antivirus (i guess with a firewall) called Nod32 wich was blocking the communication, I had to add my client "as a browser" and it sterted to work just fine. But in some other clients there are firewall preventing the communication. So, I have two questions. 1) Is there anything I can do in my client app to give the user better info about the problem? (The timeoutException does not say anything really). and... 2) What should I tell a Network Administrator that needs to be 'open' for the client to connect?   Let me know if anybody needs further info about config to answer these questions.   regards, Seba    http://sgomez.blogspot.com

WCF Tutorial - Basic Interprocess Communication

What the heck is WCF? For a long time, I couldn't tell you exactly what it was. And honestly, I still don't think I can. WCF is such a broad concept that it's hard to boil down into a concise explanation. When I finally started reading about it, and getting beyond the concepts, things started to clear up. That's what today's tutorial is about - cutting through all the concepts and just use WCF to build a basic server and a basic client.

Getting Started with Windows Communication Foundation

Windows Communication Foundation (WCF) provides a unified framework for rapidly building service-oriented applications that makes it easy to build and consume secure, reliable, and transacted Web services. It unifies the capabilities in ASMX, WSE, Remoting, COM+, and MSMQ; therefore developers need to learn only one programming model.

Event ID 1011 - DefaultAppPool World Wid Web Pub. Serv. fatal communication error

We have a Windows 2003 server running IIS6 1.1 Framework. We have also installed a DNS and Active Directory in the same machine.

We're randomly getting the error you can see below. Sometimes it causes the recycling of process w3wp.exe (which on my understanding represents the application pool worker processd) and other times results on this process hanging and not responding to any request. To do iisrest temporarly solves the problem.

We were pointed to a possible permissions problem between the user we were runnig the DefaultAppPool with and registry entries used by the iis. We noticed the default predifined user we used, Network Service, wasn't found in the Active Directory, so we changed it by the default configurable user, IWAM_MACHINE_NAME, which is under the IIS_WPG Active Directory Grupo, which, in theory has the correct permissions to run the application pool.

Well, none of this worked and we are still getting this error.

This is driving us crazy and think the problem might have to do with having the Domain Controller/Active Directory and the IIS6 running on the same machine. We'll try now uninstalling this DC pointing to another one to see what happens.

Any help would be appreciated.

Thanks in advance,

Foundations: Workflow Services for Local Communication


This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

WinInet: Enable HTTP Communication in Windows-Based Client Applications


The Internet provides the infrastructure for applications to communicate, and that can include non-UI communication between Win32-based applications. If you think beyond the standard browser usage of HTTP, you can use this protocol to retrieve information from Win32-based applications and save it to a Web server. After explaining how HTTP can be used in this way, this article shows how to use Microsoft SQL Server, ASP, IIS, WinInet, and Visual Basic to implement two examples. The first reports usage data-how often an application is used and by whom. The second monitors application errors and reports error details for use by helpdesk staff or engineers in the debugging process.
