Free inventory tool

Hi,

I want to present the Microsoft Assesment and Planning Toolkit, a powerfull free tool which seems to be very useful in an organization.
The Microsoft Assessment and Planning Toolkit performs three key functions: hardware inventory, compatibility analysis, and reporting. It collects and organizes system resources and device information from a single networked computer and does not require users to deploy software agents on the computers that must be inventoried. MAP uses technologies already available in the IT environment to perform inventory and assessments, like: Windows Management Instrumentation (WMI), the Remote Registry Service, SNMP, Active Directory Domain Services, and the Computer Browser service.
Assessments can be completed on the following Windows platforms:
Windows Vista
Windows XP Professional
Windows Server 2003 or Windows Server 2003 R2
Windows 2000 Professional or Windows 2000 Server
Windows Server 2008
The reports generated are very friendly, with a lot of excels and comprehensive graphics. It will report you, for example, how many of your Windows 2003 Server are ready, from hardware point of view, for deploying Windows 2008 on them or how many computers in your organization have Office 2003 or Office 2007 installed.
