I have a very weird problem on my hands. I have some machines in particular Dell Optiplex 745/755s that are rebooting on themselves. I ran a dell crash analysis on the machines and it came up with a Symantec file NavEx15.sys as a culprit. I am not sure if this actually is the problem because other dell models also point the navEx15.sys file as a problematic file but the other machines do not reboot. I have re-installed Symantec on these machines and I have re-imaged the machines as well. Please see the minidump log below.. any help reading this would be much welcomed.
