5. How do I configure IIS after installation?
Open IIS Manager, find your website in the 'Web Sites' folder in the left-hand pane, right-click on it and select 'Properties'. You should see a dialog box resembling the following:
Select the ISAPI Filters tab, click Add..., enter a text name in the Filter name field (e.g. “SUWA”) and then click Browse... to find and select the 'SUWA_IIS6.dll' executable file that was installed in the installation folder that you specified during WebAuth-IIS installation (If you did not change the default location it should be in “C:\Program Files\Stanford\WebAuth-IIS\”).
When both fields are set correctly click OK. You should then see the filter has been added but is not active:
Now click OK and reboot your Windows Server machine.
