Finished At Last!

All 17 motherboards at the school have been replaced and all computers freshly re-imaged. What a marathon. BTW, humidity was to blame for the blown capacitors. It turns out that the section of the building where the Computer Lab is inherited an old A/C unit which blows lots of humidity when not "conditioning". And since cool has been off for most of the summer, it got mighty tropical in there. Next year - remove all PCs and store them in the server room.
