    Hi anilsharma80 ,

     

    Is the firewall turned on in the server that is installing SQL Server? If so, please check that if you have added the TCP port and UDP port (1434) in the inbound rule of the Windows Firewall, and you can verify TCP port in SQL Server Configuration Manager.

    For more details about configuring remote access for SQL Server, please review the following blog.

    Hey anilsharma80 you don't happen to remember if this was ever resolved and what the solution was do you?

     

    I've got the same situation with a client.  When I try to run SSMS from inside their network and connect to a datamart instance, I get the same semaphore timeout.  I suspect they have restrictive firewall rules...

     

    Thanks

    Anyone figured out how to connect DataMart's SQL endpoint via SQL Mgmt Studio or Azure Studio?  

     

    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: 25 - Connection string is not valid) (.Net SqlClient Data Provider)

    Thanks in advance!
