Background: I am a teacher who set up a classroom of mac mini's out of box. The machines have one admin account and were bound to the school's active directory accounts. The students have had no problem logging into the AD accounts the past few months. Today, the machines would not work. I logged into the local admin account and went into system preferences, unbound and rebound the machine and it fixed the problem. However when I tried to log into another of the classroom mac minis, I was not able to open system preferences... It looked like it was loading, but it crashed and wouldn't open. I also noticed in finder I could not click on desktop, or documents.. I get an error that says "folder can't be opened because I do not have permission to see it's content". I tried to open the library (Go Menu, Library...) and it is completely blank. I was also not able to create screen shots, because I simply do not have permission to do that?!
I did an command R, restarted the computer and tried to correct permissions in Disk Utility.. It did not fix this problem.
This problem effects about half of my classroom machines (12 minis). I am not sure why the admin account is corrupt on them? I can't login into student accounts because of the AD problem, but the admin account is completely broken. Is my only option to reinstall the operating system? Since the mini's did not come with a OS disk, or disk drive... I will have to do the internet recovery install.. and my school's band width won't handle it. I am showing videos to the students today. Any help or advice would be greatly appreciated.
Thanks so much!
