RTC Client can not connect even when service is started.

pranav-joshi

Hello all,

I have very weird problem here.
I have about 15 NAV services installed on one server; everyone is sharing Net.Tcp Port Sharing Service.
SQL server is also installed on the same server, and all services were working fine. But suddenly I am not able to connect any database through RTC client from client machine or even from server even when all NAV server services and Net.TCP port sharing services are started.
When I am try to connect to any of these services through RTC client it is giving me following error:

Microsoft Dynamics NAV

---

The message could not be dispatched to the service at address 'net.[url=tcp://192.168.0.8:7046/DynamicsNAV/Service']tcp://192.168.0.8:7046/DynamicsNAV/Service'[/url]. Refer to the server Event Log for more details

OK

Here is the error in event viewr under system on Server where services are installed.

Thanks in advance.
