Internet access problem

Hi,

I work on a netware network with a win2000 computer accessing the internet through a linksys router to an ADSL line. The other computers that have acces to the internet all work fine. But, my win2000 computer is unable to access the internet. I can ping to say www.yahoo.com and the ip address successfully. I have been unable to find any TCP/IP setting that are incorrect. I have gone so far as to reinstall win2000 and the netware client more than once but have not been able to resolve the problem. Does anyone have a suggestion?
