I created a package that forces a reboot of client XP machines in our WAN domain using the default switch of /qn REBOOT="Force". Does the switch not work when using the "REMOTE INSTALL.. > UPGRADE WINDOWS CLIENT"? I believe it worked for me when I ran the "REMOTE INSTALL.. > WINDOWS PUSH" instead. I've been told that using UPGRADE is better for this updating. I am fairly new to this and have just started this upgrade our our ESET from version 4.7 to 5.0 (enterprise endpoint). Previous thread suggested that if machine does not reboot, then windows does not sense it needs to and ignores the force reboot switch. But, ESET comes up orange and states that it needs to reboot. I have had the Windows XP at the logon screen or had me logged on (domain admin) with same no-reboot results. Thank you for your assistance.
