Tigershark and Jareds...

The general situation here is that the individual PCs are not locked down properly, am I correct?

How many PCs are there at the school? How many IT guys are at the school itself? Are they primarily teachers with little IT training, support, or time?

Did the letter to the the School board address the District's IT program/plan/support or lack of it. If not then isn't this just addressing a symptom and possibly causing a hard working if unskilled person a great deal of grief through general FUD?

I see this situation as one of leaving internal security light and unmanaged ... but unless student records and confidential information is involved, how big a problem is it really?

I fully expect a school to control the boundaries of a campus to protect students and staff, and locking file cabinets with personal information. But leaving doors inside unlocked that allow anyone in the school to make off with an extra kickball at recess are things to control with rules and discipline.
