Question : 500 internal server error

All users cannot get to the internet. All (15 users) are getting 500 internal server error. I can get to the server onsite with Logmein IT Reach with no problem. They can send and receive email (POP 3).

Their firewall acts as a DCHP server, which is controlled from another country (parent company) and their staff IT person is on holiday so I have no access to firewall router.

From the command prompt when I ping www.cisco.com I get an address it resolves to but no response back. I ping another site of a company a friend of mine works at (hosted at Thomasnet) and get a reply back from it. When I put the IP in the browser I still get the "500 internal server error".

Thanks
