Unable to log into my Outlook mail

[Juliano degrassi]

I can log into my win2k domain, but when I open my
outlook I get prompted for username, password,and domain.
When I enter the correct info, the system replies that
it's incorrect. I have tried changing passwords and many
other fixes, including uninstalling and reinstalling
office and still can't get it to work. I can log into
outlook and my account from a different computer, but not
from mine. Scanned my computer with Norton NAV. On the
client side, using Outlook 2002, with winXP sp1, office
2002 sp1 & 2. On the server side, using echange 2000 with
sp 3, windows 2000 server with sp3.
HELP!!!

If you ping the server name do you get the correct IP address
