Finalized build last night. Ghosted both labs.
Problems:
1) on logout, unprivileged users were told that the "CA ISS Dashboard Tray" wouldn't quit. The warning timed out but didn't cancel the process on it's own. I had to uninstall AV and reinstall it (4 reboots and 25 minutes of complete scanning) as local admin user, then pull the image.
2) Ghost configuration server (on Casper) died three times, necessitating a reboot of Casper.
3) Default configs for machines seem to have been screwed up. Old configs seem to have been imposed on Lab C machines (like a default gateway etc.). I had to manually edit all of Lab C machines.
