Spiceworks simply put is an IT/Network Managers best friend. Best of all - it is FREE! Building on Spiceworks strong foundation that allows IT Managers to inventory hardware, software, and other devices via WMI the new Beta 3 now allows it's built in Help Desk to operate via LDAP and performs testing of your Exchange server. The review on Network World doesn't do the product much justice because simply put this product is a must have. It easily saves me hours of time and notifies me of any problems that otherwise would have gone undetected. Try it for yourself. I often wonder how I lived without this software before.
