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.
