Control Manager data must be stored in an SQL database. If you install Control Manager on a server that does not have its own database, the installation program provides the option to install the Microsoft Database Engine (MSDE). However, due to the limitations of MSDE, large networks require an SQL server.
Control Manager uses mixed-mode authentication, not Windows authentication, to access the SQL server.
