Este artículo se refiere a productos para los que Microsoft ya no ofrece soporte técnico. Por tanto, el presente artículo se ofrece "tal cual" y no será actualizado.

Symptoms

After you install the Proxy Server 2.0 Winsock proxy client, one of the following may occur:


  • The following error message appears after the browser is restarted:


    Internet Explorer 3.02 "An unexpected error has occurred" please restart Internet Explorer
-OR-


  • An "Internet Explorer Auto-Proxy Script download" dialog box appears, stating the following:


    Due to network or related problems, Internet Explorer could not download your Auto-Proxy Script. Do you wish to continue with standard proxy settings?


    Answering "No" produces the error message above.
-OR-


  • In Internet Explorer 4.0 for Windows 98, the error is:


    No query string
    Your client is not allowed to access the requested object.

Cause

The error message may be caused by one of the following:


  • The server specified in the URL for the script file is down.
  • Network problems are prohibiting the client from communicating with the server.
  • A problem such as permissions is preventing the script from downloading to Internet Explorer.

Workaround

Contact the system administrator to find out whether the server is down or network problems exist.


To disable the Autoconfig file, do the following in the Internet Explorer browser:


  1. Click View and then click Options.
  2. Click the Advanced tab, and then click the Automatic Configuration tab.
  3. Delete the contents of the URL box and click OK to continue.
  4. Click the Connection tab and enter a valid proxy server address (for example, http://<servername> on port 80).
  5. Click OK.
This configuration disables the JavaScript and allows the standard proxy settings to be used.

Status

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

More Information

When installing the Winsock Proxy Client, Internet Explorer clients may be configured to use a proxy autoconfiguration script. This option is disabled by default during the proxy server setup, but it may be enabled at any time, which causes the Winsock Proxy Client to configure Internet Explorer automatically.


This file, written in JavaScript, is downloaded to the client every time a Web browser is opened. This is designed to improve browser performance and to update browser configuration parameters. The script is executed against every URL that the browser requests.
