cant access hotmail on networked computer

I run win 98se on my second (networked) computer and cannot access hotmail,it keeps asking me to reenter my password.I can access hotmail no problem from my main computer(xp pro).
I have norton internet security installed on both machines and have it configured to allow access either way to both computers.
Is there anything else i need to set in order to make this work.
Do i even need norton internet security on my second computer?(98se)

Thanks
