INTRODUCTION
This article contains guidelines for installing and for uninstalling Microsoft Forefront Security for Exchange Server on a Microsoft Exchange Server 2007 standby continuous replication (SCR).



MORE INFORMATION
Standby continuous replication (SCR) is a new feature that is introduced in Microsoft Exchange Server 2007 Service Pack 1 (SP1). SCR is designed for scenarios that let users use standby recovery servers.

SCR extends the existing continuous replication features that are found in the release version of Exchange 2007. Additionally, SCR enables new data availability scenarios for mailbox servers that are running Exchange 2007 SP1.

SCR uses the same log-shipping and replay technology that is used by local continuous replication (LCR) and by cluster continuous replication (CCR) to provide added deployment options and configurations.

Guidelines for installing Forefront Security for Exchange Server on an Exchange 2007 SCR
To install Forefront Security for Exchange Server on an Exchange 2007 SCR, follow these guidelines:
 * Use a domain user account that has administrative rights to install Forefront Security for Exchange Server.
 * Install all program files to a local hard disk drive.
 * Install Forefront Security for Exchange Server only on the source server of an SCR.
 * Use the Forefront Security for Exchange Server installation procedure for an LCR if the source server is configured as a stand-alone server.
 * Use the Forefront Security for Exchange Server installation procedure for a CCR cluster if the source server is configured as CCR.
 * Use the Forefront Security for Exchange Server installation procedure for a single copy cluster (SCC) if the source server is configured as SCC.

SCR cluster notes
 The Forefront Security for Exchange Server settings will not be replicated from the source server to the target server. After a failover has occurred, Forefront Security for Exchange Server must be installed on the target server. Additionally, Forefront Security for Exchange Server must be configured to use the same settings as on the original source server. Before you install Forefront Security for Exchange Server on a target server after a failover, run the Exchange 2007 Setup command together with the /RecoverCMS option to recover the clustered mailbox server (CMS). To do this, run the following command at a command prompt:

Setup /RecoverCMS

 After a failover from the source server to the target server, you may want to reconfigure the original source server as the new target server. Before you do this, you must first uninstall Forefront Security for Exchange Server from the original source server. This is required because Forefront Security for Exchange Server must be installed only on the current source server. After you uninstall Forefront Security for Exchange Server from the original source server, run the Exchange 2007 Setup command together with the /ClearLocalCMS option to remove the original source CMS. To do this, run the following command at a command prompt:

Setup /ClearLocalCMS



Guidelines for uninstalling Forefront Security for Exchange Server from an Exchange 2007 SCR
To uninstall Forefront Security for Exchange Server from an Exchange 2007 SCR, follow these guidelines:
 * Use the Forefront Security for Exchange Server uninstallation procedure for an LCR if the source server is configured as a stand-alone server.
 * Use the Forefront Security for Exchange Server uninstallation procedure for a CCR cluster if the source server is configured as CCR.
 * Use the Forefront Security for Exchange Server uninstallation procedure for an SCC if the source server is configured as SCC.

Additional guidelines

 * Configuration data such as ScanJobs.fdb and Notifications.fdb will be associated with a CMS and not with the physical nodes. Because of this behavior, the data must be configured for each CMS only, regardless of how many nodes you have.
 * Scanner signature files are associated with a CMS so that active nodes and passive nodes will be up to date.
 * Configuration data that is kept in the registry will be replicated on a CMS basis when the CMS moves from one server to another server during a failover event.
 * When you use the Forefront Server Security Administrator console to connect to the Forefront Security for Exchange Server installation on a cluster, you must connect to the CMS. If you try to connect to the physical node, you will be prompted to select the CMS to which you want to connect.
