Check the credentials for your service. If you use windows authentication when connecting to SQL Server the the service must be run under credentials which have access to SQL Server. FOr example LocalSystem cannot access network resources.

it is mex endpoint address which can be used to test wcf service with WCF test client

First, sorry I missed your reply completely.

This doesn't make sense (at least not to me)... the WCF address should have nothing to do with the SQL connection. What if you try to use SQL Server authentication instead of Windows authentication. Also are you sure that without the mex address the WCF service is actually reached?
