Hi ,

I am getting the below exception when I am trying to ping another PC from my WCF application.
Could you please let me know any ideas/suggestions on how to resolve this issue.

An exception of type 'System.ServiceModel.FaultException`1' occurred in GlobalWcfService.dll but was not handled in user code

Additional information: remotePingServer OXF (INHYZDPC23 ): The client's security session did not receive a 'close response' 
message from the service within the configured timeout (00:01:00).

You probably got an exception inside the WCF app...but it was swallowed by this one (which only means that your connection is failty)...
Turn IncludeExceptionDetailInFaults on to see the inner exception...

Check out the eventlog on the target machine (the system running the wcf service).

I checked the Event logs in the target PC. it is as follows. can we infer anything from this.

Message : The request channel timed out while waiting for a reply after 00:00:59.9989999. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

Seems like the operation takes more than a minute to complete. You need to optimize it or increase the timeout (as needed) on both the server and client.

I have increased the sendTimeout="00:59:00" to almost 1 hour. still it is hanging and give the above time out error. Could you please let me know how to resolve this or any tips for debugging.? Thanks,Sudhakar

I would suggest running the WCF service locally in visual studio so you can debug it. Also run the client locally and connect to the local service. This gives you a better view on what is happening (and goes wrong).

Actually our application is a WCF service cum client. We need to run one instance of our application which acts as server in one PC and another instance of our application which acts as client in another PC. We can not run client and server on the same PC.Hence debugging is getting difficult.Could you please let me know if there are any other ways that we can debug and find out the problem in this case. Thanks,Sudhakar

If you have the sourcecode of both server and client it won't be a problem running them on the same machine for test purposes. If for some unexplainable reason this somehow is not possible you can always resort to a virtual machine as a virtual second development system.

I am getting the below line in the debugger when break-all (pause) the execution. " Cannot evaluate expression because a native frame is on top of the call stack" . some times it is working and sometimes it is NOT working. my code base consists of UnManaged C++ code ,Managed C++ code and C# code.
