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.
