we are using VSE 8.7 in with our EPO 4.5 server. In one of our domains the VSE protected clients perform unauthorized reboot tasks 2-3 times a day. There are no Windows event log entries on this machines regarding this task. We also performed some full scans on all of this machines but no viruses found. We have used TrendMicro in the past on this machines and we had not this problems regarding this reboot tasks. We have also reinstalled some of this problem machines, but this problem appears again after some hours.
What can we do next or what can we check to get the reason of this unauthorized reboot tasks?
