Teaching and Fighting with Active Directories

Yesterday, we have been fighting almost all day long with a thing called SnapServer and with Windows Active Directories. Was ugly but we solved a few problems; although a few are still remaining. Either there are a few incompatible concepts involved in the two system or we have some really strange issues. We'll see how it works out.
This morning, I was again teaching my FIT class. Was a good class; explained the mouse and the keyboard. Think that I found a few good analogies and was jumping around enough to keep them awake in a warm class room. Besides the two input devices, we covered the three elements of an electronic document (content, structure, and layout) and talked about the problems of spellcheckers...
Because we have only one practical session in the lab per week, we tried to fix another one. We have found a time when the class was willing to meet (Saturday @ 2pm). Then a few strange things happened that I didn't really understand. And finally we had NO class @ 2pm. Sometimes it is really hard to make sense out of the things that are happening around you. You see, I still try to get a better understanding of what is going on around me...
