SQL Server
The SQL Server is supported form version 6.5 onwards. Information about the versions prior to SQL Server 2000 however is difficult to find online, you'll have to resort to the documentation accompanying the database. Information for version 2000 can be found here.
If possible, you should use the newest driver available. The older JDBC drivers (for SQL Server 2000 and older) provided my Microsoft, are known to be buggy and slow. The new SQL Server 2005 driver is preferred and can also work with SQL Server 2000.
