Microsoft Server Operations Manager, Crissy House, announced that extended support for Windows Server 2000 would end on July 13th, 2010. House also said on this same date Windows Server 2003 (including R2) will move into its extended support lifecycle.
Further, she also aimed to “clarify some misperceptions” that there would be a third service pack release for Windows Server 2003 (and R2) in its remaining mainstream support life.
This effectively ends security updates and paid support for Windows Server 2000. Those features are still available for Server 2003 until its extended support period ends in the future.
