I already asked a similar question here: Unable to add service client for a net.tcp WCF service. The problem was solved at that time. But now the same error is coming up. My configuration of WCF service is same as that of previous question. I am again posting it here:
<system.serviceModel>
<services>
<service name="CoreService.Service1" behaviorConfiguration="beh1">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost/Service1.svc/mex" />
</baseAddresses>
</host>
<endpoint
binding="netTcpBinding"
bindingConfiguration="ultra"
contract="CoreService.IAccountService"/>
<endpoint
binding="netTcpBinding"
bindingConfiguration="ultra"
contract="CoreService.IBoardService"/>
<endpoint
binding="netTcpBinding"
bindingConfiguration="ultra"
contract="CoreService.ICategoryService"/>
<endpoint
address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange"/>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="ultra"
maxBufferPoolSize="2147483647"
maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647"

<security mode="None">
<message clientCredentialType="None"/>
<transport protectionLevel="None" clientCredentialType="None"/>
</security>
<reliableSession enabled="false"/>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="beh1">
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="True" />
<dataContractSerializer maxItemsInObjectGraph="65536" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
The error is:
The URI prefix is not recognized. Metadata contains a reference that
cannot be resolved: 'net.tcp://localhost/Service1.svc'. Could not
connect to net.tcp://localhost/Service1.svc. The connection attempt
lasted for a time span of 00:00:02.0051147. TCP error code 10061: No
connection could be made because the target machine actively refused
it 127.0.0.1:808. No connection could be made because the target
machine actively refused it 127.0.0.1:808 If the service is defined in
the current solution, try building the solution and adding the service
reference again.
After the problem was solved, I didn't made any changes to the configuration and after some days it started showing that error again. I tried everything but nothing worked. Please help!
UPDATE: I am also able to access it using HTTP through my browser but unable to access using "Add Service Reference" option through net.tcp protocol.

Finally with the help of this link: http://rohitguptablog.wordpress.com/2011/06/16/configuring-wcf-service-with-nettcpbinding/, I figured out what was going wrong. Actually I missed the third step in above link. The Net.Tcp services were not running.
