The Forefront Client Security Deployment Tool is a free toolkit that is meant to provide additional deployment capabilities in addition to those who are available with the RTM Version of FCS . This tool gives network and security administrators the ability to scan their network and/or AD, discover existing solutions that are already installed on their clients, uninstall the existing solution and install FCS Client – all in one.
