Consistent access denied / Login prompt and HTTP 401 errors in IISLOG when trying to open up Central Admin in SharePoint 2013


SharePoint 2013 installation went well without any errors, however, I was not able to get to Central Admin. It consistently gave me access denied error message and login prompt.


After a great deal of troubleshooting, it turned out that there was a setting in IIS that needed to be corrected. This setting is easy to overlook. There could be other settings that could lead to similar behavior, But this one worked for me.

Here is the entry I needed to create.


Here is how I created it:

  • Go to IIS Manager (inetmgr.exe)
  • Select Server name from left pane, go to Authorization Rules
  • Right click anywhere on the body section and add
  • Select “All Anonymous Users” section and click ok

This loaded the Central Admin for me.
