I'm hosting a WCF service in IIS7 on Windows Server 08, sp2. The service is hosted as its own website and is exposed via a NET.TCP endpoint. The service works perfectly until a restart/iisreset command is issued.
After restart or iisreset, when I make any service call, I receive the following error: 'System.ServiceModel.EndpointNotFoundException: The message could not be dispatched because the service at the endpoint address 'net.tcp://[website]/[service_name].svc' is unavailable for the protocol of the address.. '
The server's event log shows the following error: 'An error occurred while trying to read and instantiate the configured ProcessHandlerType. Exception: System.ArgumentException Message: Unknown protocol ID 'NET.TCP'. StackTrace: at System.Web.Hosting.ProcessHost.StartProcessProtocolListenerChannel(String protocolId, IListenerChannelCallback listenerChannelCallback) '
Question: How do I fix this? Why is the NET.TCP protocol disabled after iisreset? Is it a bug? Am I missing some configuration?
IIS setup details: - Server 08 and 08 R2 - Bindings: http, NET.TCP (808:*) - EnabledProtols: http,NET.TCP. - The identity for the site's appPool is set to a specific user.
