Last December we did updates on all the Windows 7 images and uploaded them back to the server. And they worked. But now, anytime we have to update the windows OS the images the image fails (whether we multicast or not). The client just stops, no errors or anything. On the master it responds with "All connections lost". Tried updating to the latest version of zcm and nothing changed. And it always stops at a specific file. We use to get segmentation faults when we had problems with ZCM but we are not even getting those now. And we could usually fix Segmentation faults. But now even when we create a new OS image of windows 7 it still fails on the same file. That file name is "presentationfontcache.exe.config"
