IE6 and WIN98 and VERIZON

I am doing network upgrades for a company and one of their machines is windows 98se I installed ie6 sp1. I installed this on the other machines which have windows xp.

The problem is when they loging to their dsl web email site, the xp machines have no problems, but the win98 machine has every look that it is authenticateing correctly and downloads the objects but at the last second it hangs on the last image and redirects back to the initial login prompt. I get no errors and no login failure messages on the site.

I tried to call verizon to see if I could get their internet explorer requirment to view the site but they had none. I have tried to change ie settings but to no avail…what the hell is going on?
