You try to create the Symantec Endpoint Protection Manager database on your SQL server. You see the message, "Error 11501: Unable to create the database for Symantec Endpoint Protection Manager" or "Unable to connect to the database".
There are two problems that can cause this error message to appear.
Network connectivity between the Symantec Endpoint Protection Manager and the Microsoft SQL Server is unavailable
Ensure that the Symantec Endpoint Protection Manager can communicate with the SQL server.
Ensure that the SQL server's IP address is entered correctly in the Server Configuration Wizard on the Manager.
Use the ping command to determine whether network traffic can flow between the Manager and the SQL server.
The TCP/IP protocol is disabled in Microsoft SQL Server itself
In this case, enable the TCP/IP protocol in Microsoft SQL Server. To enable TCP/IP, follow the instructions for your version of Microsoft SQL Server:
Once you enable the TCP/IP protocol, restart the SQL Server service.
