WCF on a workgroup - wcf

Question

I have developed WCF windows service using net tcp binding. Its working fine when wcf client and wcf service both are in domain (in two different system)
Getting error when both system are in work group not in domain
please suggest what configuration i need to change .
Error :System.ServiceModel.CommunicationException: 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 '00:00:58.9879193'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Answer 1

According to the information you provide, it is very likely that the error is caused by the large amount of transmitted data. NetTcpbing will have a higher transmission performance in the local area network. SO you have no errors in the same domain. The WCF default timeout period is 1 minute. If the data is not transmitted within a minute, an error will be reported. I suggest you extend the timeout period on the server side:
<bindings>
<netTcpBinding>
<binding openTimeout="00:10:00"
closeTimeout="00:10:00"
sendTimeout="00:10:00"
receiveTimeout="00:20:00">
</binding>
</netTcpBinding>
</bindings>
Besides, please enable the windows feature for supporting NetTCP protocol.
Feel free to let me know if the problem persists.
UPDATE
If the client and server are not on the same machine, the client needs to provide windows credentials, because nettcpbinding defaults to windows authentication:
ServiceReference1.CalculatorClient calculatorClient = new ServiceReference1.CalculatorClient();
calculatorClient.ClientCredentials.Windows.ClientCredential.UserName = "Administrator";
calculatorClient.ClientCredentials.Windows.ClientCredential.Password = "Password";
If this problem still exists, it is recommended to add a mex endpoint:
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange"></endpoint>
Set the Mode value to Message:
<binding name="Binding">
<security mode="Message">
<message clientCredentialType="Certificate" />
</security>
</binding>
In your configuration file, I found that you did not set the value of Mode.
This is my App.config:
