January 17, 2003[From Microsoft]
SQL Server 2000 Service Pack 3 (SP3) addresses specific issues discovered in SQL Server 2000 since its ship date.
Because SQL Server Service Packs are cumulative, SP3 includes all fixes from previously released Service Pack 1 (SP1) and Service Pack 2 (SP2), and can be applied to an original installation or to one where SP1 or SP2 was previously applied.
