I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Could be a number of reasons.
1. Logged on user has Internet rights?
2. IP configuration of server
3. ping tests - can you ping other servers? external site?
4. DNS is able to resolve website names?

The user has internet access which is the administrator ,primary dns settings are correct and can ping proxy server with all dns servers. when I bypass the proxy over firewall im able to get onto the internet ,but the server needs to connect to the proxy.

Many Thanks
If you bypass the proxy server and it's able to get through to the Internet then nothing is wrong with IE. The issue is with the proxy server accepting  traffic from this server.
