Intranet accessed problem

My workstation is running on Win98SE and this PC is facing the failure on accessing on our
Intranet website,hosted on a Win2000 server which is also a DHCP and a DNS server.
My workstation is using a dynamic address assigned from a DHCP server.I have
no problem on accessing
the intranet on other workstation.Even worst is I can ping the IP address and host name of my
Win2k intranet webserver but still I can’t get the website despite putting in a correct address
of my webserver.
Pls advise.
