I've been meaning to ask this for a while so figured I would while I have it in mind. I have a Windows 2003/XP based network with about 40 managed PC's. Monthly I have to use eEye Retina to do a vulnerability scan and upchannel/remediate the findings. The problem is, if I run the scan and a user has shut down the PC, Retina is denied access and I then I have to track down the offending PC and have it powered up, then re-scan. Is there a script or command line argument that would allow me to ping a range of PC's either by name or IP range? This way I can find the offending PC and power it up before running the initial scan (I can't deny users the right to power down, btw, just would rather they not do it inadvertently). Thanks.
