A hotfix is available for System Center Configuration Manager 2007 SP2 clients to improve the functionality of virtual machines that are managed by Microsoft Enterprise Desktop Virtualization version 2

This hotfix adds new functionality to Microsoft Enterprise Desktop Virtualization virtual machines that are configured in NAT mode to use host computer location boundaries on an intranet. When a System Center Configuration Manager client detects that the virtual machine is located on an intranet, this hotfix enables roaming support for assigning a site automatically and for locating the closest distribution points. For the administrator to manage the virtual machines and the host computer in the same manner on intranet, the host computer cannot be in NAT mode. However, not all features are supported when you manage the virtual machines by using this mechanism. Some features that require communication with the virtual machines in NAT mode from the System Center Configuration Manager site server are not supported. For example, Remote Control and Client Push are not supported.

NAT mode is supported in an Internet-based client management configuration in System Center Configuration Manager 2007 without installing the hotfix. However, Internet-based client management does not support roaming (Roaming lets clients find the closest distribution points to download content). Clients that are managed over an Internet connection have a fixed Internet-based management point. Clients communicate with the fixed management point when they are on the Internet to find Internet-facing distribution points to download content.
