Some computers can ping web IP address but cannot resolve ip to domain name

[Kev]

We have a small business network consists of 15 computers. 2 people
bring their own laptop in to connect to our network.

I have tried both a linksys and d-link router. Some computers can
connect to the internet using ip address but not by domain name.
(Cannot resolve from domain name to IP).

Please advise. Tried changing DNS server to 3 different ones, not
doing a thing.

An interesting observation, 2 SBS servers can both connect online, 1
Win XP can connect via anonymizer, while all the other Win XP cannot
connect except the 2 laptops.

Please advise.

Thanks.

Hi Kev,

How are the PCs configured? Are they getting an IP address via DCHP,
or are they static addresses?

If you haven't done so already, my first suggestion would be to open a
command prompt window and run IPCONFIG /ALL on a PC that works. Then
do the same on a PC that doesn't work, and compare the output. Make
sure the DNS addresses are the same for each.
