Hi Everyone, I am checking how to exclude PCs which is not connected to the domain for certain periods of times from the collection. We cannot remove those PCs as we need to keep it in our DB as long as PC accounts are valid (meaning they are active and is connecting to domain but on rare occasions). But at the same time, need to exclude those PCs from the collection to improve numbers on the number of clients reporting to SCCM site. Could you advise on the following items: 1) Agent time : how SCCM collect agent time? 2) Active : How SCCM mark clients as active or not active? http://img716.imageshack.us/img716/5318/18684590.jpg http://img176.imageshack.us/img176/3114/10136115.jpg Thanks in advance,
