Enterprise Vault supports SQL Server 2000, 2005, and 2008.
Both Windows Authentication mode and with Mixed Mode Authentication are supported.
The SQL installation must be case-insensitive, as case-sensitive SQL installations are not supported.
Note that if both Enterprise Vault and SQL Server are installed on the same Windows Server 2003 computer, you will need at least SQL Server 2000 with Service Pack 4. Windows Server 2008 requires SQL Server 2005 SP2 or later.
