This release enables two new key feature areas/scenarios:
Network Access Protection – in conjunction with the Windows Server “Longhorn” Network Access Protection (NAP) feature, you can use Configuration Manager 2007 Beta 1 Refresh to restrict network access for computers that do not have security updates you identify as required. They can then be required to install the necessary updates before being given full network access.
Windows Vista Deployment – Using the Operating System Deployment (OSD) feature, you can now deploy Windows Vista Beta 2 (build 5384.4) to computers managed by Configuration Manager. Please note that versions of Vista other than the official Beta 2 release (build 5384), both older and newer, are currently not supported and will not work properly with OS Deployment in Configuration Manager 2007 Beta 1 Refresh.
For additional details, be sure to download and review the updated product documentation also available at the Microsoft Connect site for Configuration Manager 2007 Beta.
