Service Pack 2 for Exchange Server 2000 is available for download
here.
The same download updates both Exchange 2000 Server and Exchange
2000 Enterprise Server.
You must install Windows 2000 Service Pack 2
before installing Exchange 2000 SP2. You cannot remove SP2 without
removing and restoring Exchange to the original system state. SP2
upgrades databases to a new version. For other critical issues that
you should consider when planning your SP2 rollout, see:
Exchange 2000 SP2
includes fixes that were previously publicly available. However, it
does not include certain post-SP1 hotfixes that were available only
from Microsoft Product Support Services (PSS). PSS will have
information on which fixes are included and, for those that are not,
whether SP2 updates are available. For details, see:
