certain pc unable to access internet

[aeiou9]

I use win2k server running dhcp.
Suppose that all the pc, with the setting dns is checked disable.
but some of the pc (fixed location) can't even access to the internet.
So i enable the dns for the pc that couldnt access to the internet, it works. but some of the website is unaccessible. i try to ping it, error msg, "unknown host".

for the other pc that can access to internet, they can view all the website with no problems at all.

More detail is needed about this configuration. It sounds like a name resolution problem, what are the specifics on the PC network configs?
