These are the steps to remove Microsoft Forefront Protection 2010 for Exchange Server (FPE) from a CCR system. The Add or Remove Programs tool takes the CMS offline on the active node. You do not have to stop services in order to uninstall FPE from a CCR system.

Do not restart any computer until FPE is uninstalled on all nodes, even if the uninstaller prompts you to do so. Otherwise, if an active node is restarted, the CMS running on that node may move to a passive node before the passive node can be uninstalled successfully. Do not manually move any CMS until FPE has been uninstalled on all nodes.

Uninstall FPE from the active node first, then from the passive node.

To uninstall from a CCR system
  1. In the Control Panel, double-click Add or Remove Programs.

  2. Select Microsoft Forefront Server Protection and click Remove. When you are asked to confirm your decision, click Yes. When uninstalling from clustered servers, the Remove Program tool takes the CMS offline on the active node.

  3. After FPE has been removed from the active node, repeat steps 1-2 for the passive node.
