Windows 2000 Proxy service

Check to see if you have the correct network protocol loaded ..ie TCP/IP and that it is working. To check run a dos box and type ping 127.0.0.1 you should get 4 positve replys.
If this is ok.. then in dos box type ipconfig /all and see if it can find the host.
You may have to type ipconfig /release then ipconfig /renew then try /all again.

Hope this helps

If you don't have any connectivity problem ie you can ping your server by its IP address and name. Then try to make use of the browser. If you cannot then you should check if your web browser proxy settings are correct ( compare it to a well configured machine ). If the browser is working fine but mail is not then you should check with your administrator to see if your IP address is within the LAT ( Local Address Table ).

There's also a program located in the client proxy setup directory that can help you do the last check : chkwsp32.exe

Robert,
What does not work? The Internet? Other subnets?

If it's the Internet, check to make sure you set the Browser right. Go to Tools, Internet Options, Connections, and run the setup again. If you not sure about your proxy configs (you mentioned to have set the client already), just let the browser find the settings automatically. But, run the setup again.
Also, if it's a network problem (not internet), run the command prompt, run ipconfig == realease /all, renew /all. To reset yourNIC.

Good luck!

The fact that you cannot ping the Proxy server may not be critical. The default installation of proxy disables the ping response for security purposes. Can you ping the proxy from a working machine? The normal method to install the proxy client is from a share on the proxy server. Were you able to access this share or did you install the client another way?
One other point to consider, is that the default proxy access is "No Access". Does your user account work on a different working platform?With so little information to go on, I have no answers, only a little troubleshooting help.
