SYMPTOMS
If you use a Cisco PIX 520 firewall to secure network access, and Internet Explorer is configured to use a proxy automatic configuration (PAC) file behind the firewall, Internet Explorer may prompt you four times for your user name and password before you can gain access to the network. This problem occurs if anonymous access is disabled for the PAC file and basic authentication is required.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Internet Explorer 5.5 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:   Date         Time   Version         Size     File name 17-Dec-2001 13:25  5.50.4912.1700  481,040  Wininet.dll



WORKAROUND
To work around this behavior, enable anonymous access to the PAC file.
