This was 15 years ago. We had just rolled out Deep Freeze to a handful of labs across our district, but not to the teachers (who had local documents) and the 4 student PCs in the classrooms - yes each class had 5 PCs total.

Our problem with Deep Freeze was getting it to work nice with our locally installed software mixed our custom Novell stack that pushed software dynamically based on logged in users. So we relegated it to computer labs that had no local software.
