ADDING ANONYMOUS ACCESS TO AN EXISTING WEB APPLICATION
If you don’t select the Allow Anonymous Access option while creating a web application, you
can enable it later. Go to Central Administration Application Management Manage Web
Applications. Choose the web application, and click the Authentication Providers button.
Then click the zone (based on the URL the users use to get to the web application’s contents) on
which you want to allow anonymous access. (Zones are discussed in the “Alternate Access Mapping”
section. For now, we have only the Default zone.) When you click the zone, you will be taken to the
Edit Authentication page.
Select the Enable Anonymous Access box and click Save to permit anonymous access for this web

When you are in the Manage Web Applications page, if you select a web application, you
can click the Anonymous Policy button to display the Anonymous Access Restrictions page
(Figure 10.58) and apply restrictions to anonymous access.
These settings override any settings for anonymous access applied at the site collection (or
lower) level. So, you can force any anonymous access for the entire web application to Deny
Write or Deny All, regardless of what the site administrator of the enclosed site collection does
(none means no restrictions are set from this level). Deny All is the equivalent of disabling
anonymous access completely on the Authentication Providers page, except that it leaves anonymous
access as a conigurable option in the site collections—so the individual site collections can have
anonymous access permissions configured, but they’re all disabled when this restriction is in
This approach is handy if you need to disable all anonymous access on a web application
temporarily (without having to redo all the permissions on each site collection).
