Changing Store Limits in Exchange 2003 SP2

By default, the size limit of each database on a server running Exchange 2000 and Exchange Server 2003 Standard Edition is 16 GB (this limit is also enforced in SBS 2000/2003). Exchange Server 2003 Service Pack 2 (SP2) is supposed to remove this limit and thus allow for further DB size growth.
