Hello everyone. 

I recently started noticing that my desktop machine will not reboot or shutdown without being forced. Its triggering an event 1073. I have AV, PTP, and NTP installed on the affected client. I also have a laptop with the same installation. Its it not being affected in this regard. When I uninstall the client shutdown/reboot works normally. Opon reinstallation the behavior returns. I have performed an uninstall, test, reinstall several times and the the behavior is consistant.

So far google searches have not yielded any solution.

Does anyone have any idea what might be going on? 

Thanks for your time.

Sam
