SCCM 2012: Setup is unable to connect to SQL Server

There is a big change that you catch the underneath error during your SCCM 2012 deployment:

 Setup is unable to connect to SQL Server with the connection information provided. Verify the following:

– The SQL Server and instance names are entered correctly
– The specified SQL Server instance is not configured to use dynamic ports
– If a firewall is enabled on the SQL Server, inbout rules exist to allow connections to the correct ports
– The account used to run Setup has permissions to connect to the specified SQL server instance

Open the “SQL Server Configuration manager” and Naviagte to The Protocols of your SQL Instance in the “SQL Server Network Configuration”

Enable “Named Pipes” and “TCP/IP”

Restart the SQL Service Instance within the SQL Server Services:

This seems to be a common issue during the SCCM 2012 setup:  Windows-Noobs

Verify also that you are running the one of the supported  SQL versions:

– SQL Server 2008 SP2 with Cumulative Update 9
– SQL Server 2008 SP3 with Cumulative Update 4
– SQL Server 2008 R2 with SP1 and Cumulative Update 4

      Thank you for you reply. The problem was in incorrect setup of TCP ports (not dynamic), after i setup it everything works fine. Thank you

    Thanks, I was tempted to switch off the firewall but read that ConfigMgr does require component to be active this to report a healthy state.
