Hey!! Stop shoutinggg! For a start, can you confirm the DHCP is dishing out the correct gateway to the clients by typing an ipconfig/all command on your clients?

Just some thoughts:

Have you checked that the machines can do name resolution?
Open up a Dos Window and type in NSLookup, then try to resolve some external name i.e. tek-tips.com.

Quick fix would be to point them at the same DNS settings as the Server is using.

If your using DNS on the 2003 server check that the DNS server can resolve names. The IE browser is, mostly likely, only using the details from the NIC settings.

Do you have a firewall that may be blocking certain ip addresses for access external sites?
