I've deployed the agent (ZCM 10SP1) to two different test workstations so far, an Inspiron 8100 laptop, and a GX260 desktop. Each hung during reboot at the Windows is Shutting Down screen, which returned a "failed" message to ZCM. I had to manually power them off, after which the status changed to success.

This behavior used to happen with the ZPM agent and it caused errors on the hard drive.

I can't find anything in Event Viewer. Is this common behavior? Is there a consistent reason this happens?
