windows 98 login script problem?

Hi everyone!!!
I have just reformated my laptop hard drive and reinstall windows 98. Every thing works perfectly but when I try to log in to windows 2000 domain, the login script pops up as if it’s processing but disappear very quickly. Then I checked my computer but there’s nothing map to server shares.

Note that every other windows 98 have no problem with the login script. The script use %username% variable. I really have no idea why this particular machine wont process the login script.Can anyone help me out on this problem, would be very appreciated ?
Thanks
