​If the students are getting an error message when they try to logon about ‘not enough resources are available’, they need to be restarted.  After they press Alt+Ctrl+ Del there is a red box in the lower right hand corner that they can click on to do it or just hold the power button down until the computer turns off then turn it back on.

It’s important that you instruct student to SHUT DOWN the computers when they are done using them.
