    There was no endpoint listening at net.tcp://localhost/TNA/TAServices/AuthenticationManager/mex that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

If you would like more help, type "svcutil /?"

After rebooting the system and immediately executing below command would listen

    Metadata contains a reference that cannot be resolved: 'net.tcp://localhost/TNA/TAServices/AuthenticationManager'.

    The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:04:59.9843782'.

    An existing connection was forcibly closed by the remote host

It wasn't overwritten by another process.

But below log shows it was overwritten by some other process not by SMSvcHost

An error occurred in the Activation Service 'NetTcpActivator' of the protocol 'net.tcp' while trying to listen for the site '1', thus the protocol is disabled for the site temporarily. See the exception message for more details.

How should I need to configure windows and web.config file so that the process SMSvcHost would listen first after every boot. So that I wouldn't establish another listener by default by some other process on IP endpoint 0.0.0.0:808

Answer 1

As you know, NetTcp binding by default listens to the request on the 808 port. Therefore, please ensure the port 808 has not been used by another website when hosting the WCF service in IIS. Alternatively, we had better change another port in the site binding configuration.
WCF net.tcp binding 808:* what does this mean?
Besides, in order to support the NetTcp protocol in IIS, please refer to the below link.
Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Base address schemes are [http]
Finally, the configuration file of the WCF service doesn't support Nettcp protocol, we should add a service endpoint with NetTcpbinding so that it can work over NetTcp` protocol.
Feel free to let me know if there is anything I can help with.
