Connectivity Rules SQL
These rules check the SQL Server machine is running and is accessible over the network.
The Rules range from the basic ping to much stronger tests such as Win32 API remote invocation and remote logon to the SQL Server.
To perform a test logon to the SQL Server, select “Logon to SQL Server of Instance” and leave the instance name blank — this connects to the default instance of “MSSQL“.
Of course, if you’ve changed the instance name, add it.
