SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I'm stumped by an access phenomenon because I am not sure how the permisssons for accessing a site collection work in this specific scenario:

Even though I shouln't be able to do so, I am accessing my site collection via Webbrowser logged on as my built-in local windows administrator (BUILTIN/Administrator) (who is also a farm administrator).

  • BUILTIN/Administrator is not a site collection admin
  • BUILTIN/Administrator is not a member in any site collection group

And according to this technet documentation by Microsoft I shouldn't be allowed to access my site collection! Can someone explain how come I can still access my site collection anyway?

All other user accounts that are members of the windows administrators group get the access denied error. Only BUILTIN/Administrator does not.

I'm currently doing security consulting work and need clearity on this issue.

Note: I am using a SharePoint 2010 Foundation standalone installation on Windows Server 2008 R2 Standard.

Check your web application user policy and see if builtin\administrators have full control.

That did the trick! My BUILTIN/Administrator did have full control for the web application and no other user did. Thanks for the hint! :-) –  Robert Jost May 31 '12 at 15:57

Before you remove that user check that you're not using it as Search content access account –  Per Jakobsen May 31 '12 at 18:35
