PS/2 port issues on NetServer LH Pro

[Jason_428]

Recently while setting up a Lab for a class all of the NetServer Pros lost the ability to use a mouse on the PS/2 port. This causes a problem since it is a lab and these are the only mice we have.

Does anyone know what might have caused this and how I can fix it? Or can someone point me in the right direction to where I could find the anwser?

I have already used HP's site and google.com to search for and come up empty handed
