I also posted this in the Agent Deployment section but I figured it probably belongs in the imaging section. Here goes:

We have 10.2.1 on a W2k3 backend, quite a few of our agents are still on 10.2 though. The update has been planned for the near future. Our workstations have XPSP3. For some reason some PC's that have been working okay for a while decide they need a fresh install and pull themselves an image from the server. It turns out the ImageSafe data has been cleared out returning these PC's to bare metal state. Funny thing is: we have no imaging policies assigned to these workstations of workstationfolders. We know that some PC's that faced this issue had the 10.2 agent, we're not sure it's a problem with the 10.2.1 agent, though.
