I was using my laptop on a hotel wireless the past couple of days. I returned home and put it back on the docking station. However, I do remember getting this same error message while I was on the hotel wireless. Since IE worked, I didn't worry about it, thinking it had something to do with the hotel wireless. However, now I'm home and it still won't work. I've uninstalled and reinstalled firefox a couple of times - still the same error message. I don't have a "system administrator" to contact - that would be me!
