Failed GPIB0 AT-GPIB/*****

I have a fresh reinstall of NI 488.2 While going through the Troubleshooting Wizard

I get the following;

GPIB0    AT-GPIB/*****    Failed

GPIB1    AT-GPIB/*****    Failed

GPIB2    PCI-GPIB          Passed

GPIB3   AT-GPIB/*****    Failed

GPIB4   AT-GPIB/*****    Failed

All of  the AT-GPIB/***** Failed, 

The Device Status is;

This Device is not present, Not working properly,

or does not have all the drivers installed. See your Hardware documentation (code 24)

I'm not sure if I should have this many devices, I have two instruments I'm trying to control

an HP 3570 and an HP 3330B.

Also, what is the difference between a PCI-GPIB and an AT-GPIB/*****?

This is an old system running on Windows 95.
