To enable anonymous access for a SharePoint site: 

  1. Open the site on which you want to enable anonymous access.
  2. On the Site Actions menu, click Site Permissions.
  3. Under Permission Tools > Edit, click Anonymous Access in the Manage section.
  4. In the Anonymous Access window, select the parts of your website that you want anonymous users to access.

 

To enable anonymous access on a list or library:

Use this procedure only if you have enabled anonymous access on your site as described in the previous procedure and have granted access to either the entire web site or just to lists and libraries, as described in step 4 above.
The following steps can only be performed on a list or library that is using unique permissions.

  1. Open the list or library on which you want to enable anonymous access.
  2. In the List Tools > List > Settings section, click List Permissions.

    .

    Note: The Settings menu is not available on the Permissions page if your list or library is inheriting permissions from its parent site. If your list or library is inheriting permissions from the site, you must first break the inheritance from the site. To do so, in the Inheritance section, click Stop Inheriting Permissions.

  3. In the Permission Tools > Edit > Manage section, click Anonymous Access.
  4. In the Anonymous Access window, select the permissions that you want to grant to anonymous users for this list or library.

Note: Only the View Item permission is available for libraries. This is to help protect your site from potential script injection attacks.
