if the machine still have access to the other network resources, it might be
a problem with DNS not knowing how to interpret internet addresses.
- Check the connection to the dns server
- Can it be that there is a software that controls access to the internet?
like the ones for parents controlling to what sites and what times the kids
connect to the network. hmm ask your parents :-p
- check the logs to see if there is problem with the network or services.

hope th shelps,
