I am looking to the AO community for some recomendations about Asset Management Software. The company I work for has around 500+ machines and we are looking into purchasing some Asset Management Software to inventory and help us manage the growing number of computers. I would personally also like it to go above and beyond Asset Management with features such as patch management and the likes. We have been testing a few products such as ZENworks from Novell and two to three other products that do and are about the same.

If you have any expirience in this area and or there are any products you like over others please let me know.
