I have a WCF service run on Windows Server 2008 RC2 IIS 7 with no firewall. When I trying to call it with netTcpBinding binding, I get this exception:
System.TimeoutException: The open operation did not complete within the allotted timeout of 00:00:30. The time allotted to this operation may have been a portion of a longer timeout. ---> System.TimeoutException: The socket transfer timed out after 00:00:30. You have exceeded the timeout set on your binding. The time allotted to this operation may have been a portion of a longer timeout. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.ServiceModel.Channels.SocketConnection.ReadCore(Byte[] buffer, Int32 offset, Int32 size, TimeSpan timeout, Boolean closing)...
The method I call just returns a numeric value, nothing else, so the problem not in timeout. If I use wsHttpBinding - it works without problems. Also I added logging to method I call, so I know that it even not executed.
I made all steps to configure IIS from here. The questions are:
- Anybody know what the problem may be?
- How can I troubleshoot/debug this problem?
