If you finished developing your SharePoint based website and you would like to make your site or part of it available to everyone in your organization or available via Internet you have reached the right place. I would like to note that Anonymous Access is not for everyone and needs to be planned out carefully.
Access SharePoint 2010 Enterprise SP1 W/ Anonymous Access Environment Now
So let’s begin!
1.) Navigate to SharePoint 2010 Central Administration -> Application management -> Manage web applications.
2.) Choose the web application
you would like to configure and click on Authentication Providers.
3.) Click on Default
4.) On the Edit Authentication
screen choose the Enable anonymous access
option and click on save.
5.) Our next step is to open your SharePoint site
-> Site Actions
-> Site Permissions
6.) Click on Anonymous Access
7.) Specify which parts of your web site you would like to enable anonymous access
for and click on OK
8.) Notice that a new entry was added to the list of permissions
9.) Navigate to Site Actions
-> Site Settings
10.) Navigate to Galleries
-> Master Pages and page layouts
11.) Click on the library tab
12.) Click on Library Permissions
13.) Click on Anonymous Access
14.) Specify the permission level of anonymous users. In our case we would like anonymous users to be able to view items.
15.) Navigate to Site Actions –> View All Site Content
16.) Click on Style Library
and repeat the actions in steps 11 – 14.
17.) That’s it! Now we can test our configuration. Sign out of your web site, close your browser and then reopen.
Great! If we see the ” Sign In” button on the top of the screen that means our configuration is correct and we can access the site anonymously.
