Due to unexpected problems with the Windows Server, the Windows lab machines do not work.
We will update you as progress happens.
Update 01/19 at 09:17 PM: We were able to implement a temporary solution so that some of the Windows computers in the lab work (as well as some of the Linux computers). The computers with blue post-it notes definitely do not work. The others worked when last checked. We apologize for the inconvenience.
Update 01/20: The machines previously with blue post-it notes are now working. All computers should be working as before.
