When I manage my printer broker and attempt to upload new driver, I get
a message that says "Error on Page" on my IE status bar. My coworker
has no problem. We're both running Windows XP SP2 and IE 6.0.29.

What could the problem be?

Here's the full details of my config:

Netware 6.5 SP4a
iManager 2.5.20050809
iPrint Management Plugin 2.02.20060224

Windows XP SP2
Internet Explorer 6.0.2900.2180
