The Microsoft Assessment and Planning (MAP) Toolkit is a powerful inventory, assessment, and reporting tool that can securely inventory small or large IT environments without requiring the installation of any agent software. The data and analysis that this tool provides can significantly simplify the planning process for a wide range of migration projects. This automation tool helps IT professionals and consultants establish a clearer understanding of your infrastructure, desktop, and virtualization needs through network-wide assessment of your assets including desktops, laptops, servers, applications and network devices. The tool uses a Graphical User Interface (GUI) that is familiar and easy to use. This paper explains how to utilize it to "map" your infrastructure for Windows 7 and Server 2008.
