RTC connection error

Please help am getting the below error

Microsoft Dynamics NAV

There was no endpoint listening at net.tcp://localhost:7046/DynamicsNAV/Service that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.


Welcome to DUG!!!.

I think maybe you have entered the wrong ServerInstance.

Check it in the CustomSettings.config file…

Thanks Amol.

I have changed the CustomSetting file. And now am getting the bellow error. Am on Nav 2009 and using SQL express.

Microsoft Dynamics NAV

The Microsoft Dynamics NAV Server cannot connect the Change Listener to SQL Server because of the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Hi I have the same problem but i can access to RTC just from the Machine that host NAV Server , I tryed from other machine But i get the error:

the login failed when you connect to Sql Server

Are you using same account from both machines or different?

check whether you have added account in NAV users…
