we are using a ms proxy server2.0 to get to the internet,we have no problems with this set up, when trying to access a password protected part of our website out on the internet we get the access denied 401.3 error , if we go out to the internet from a dial up or directly from the proxy server it askes for the user name and password which is what we want, but why won't it do this going through the proxy server

What you are trying to d is a reverse proxy request (Internal user > proxy server > internal web server). Here is literature from Technet.

The Proxy Server tries to validate the Internet user and sends back the Proxy Authentication header that the browser is not designed to recognize. Therefore, the user will be prompted for username and password three times, then access will be denied, regardless of what username the user enters.

Solutions are install SP1 fro Proxy 2.0 or disable access controls for the web proxy service.
