Unable to Access an IIS Web Site That Requires Integrated Authentication With AV Enabled

noteA Web server running IIS (Internet Information Services) can have authentication configured in two ways:
  • Basic Authentication - Access is permitted over a NetScreen firewall that has AV enabled on a policy.
  • Integrated Authentication - Access is denied over a NetScreen firewall with AV enabled on a policy. A "Page Not Found" error will display with no authentication prompt.

Open the WebUI. For more information on accessing the WebUI, go to Accessing Your NetScreen Device Using the WebUI.

From the NetScreen options menu, click Screening, select Antivirus, and then click Global.
