Connecting Through Proxy Prompts for Authentication

Article ID: 170042

Article Last Modified on 8/13/1999



APPLIES TO

  • Microsoft Proxy Server 1.0 Standard Edition



This article was previously published under Q170042

SYMPTOMS

When you try to access Internet sites through a Proxy Server, your browser will display a login dialog box trying to authenticate you. If you leave the username and password blank, and you press Enter, which again brings up the login dialog box (this happens 5 or 6 times), before your browser displays the site.

CAUSE

You have insufficient permissions on the following folders in Microsoft Windows NT Server version 4.0:

/InetPub/Scripts
/Urlcache folder


This usually happens when you try to access sites that are returning cookies.

WORKAROUND

Check the permissions on the /Inetpub/Scripts and see if Everyone has full control. Check the permissions for the urlcache directory; Everyone needs Read/Execute (RX) on the above directories.

  1. Open Windows NT Explorer, and select the Scripts subfolder, under the Inetpub folder.
  2. Right click Properties, and click the Security tab. Then click the Permissions tab. Add the group Everyone, and select Full Control for type of access. Click OK.
  3. Do the same for the Urlcache folder and for the type of access select Read/Execute (RX).

From your browser type the URL of an Internet site. You should not be prompted with a login id screen anymore. You should be able to access the site as Anonymous user as long as this option is selected for Password Authentication.

NOTE: Also refer to the online documentation on how to set the Password Authentication and information on how each of these options work.
