Disable Loop Back Check in SharePoint 2013



When you access SharePoint web apps from the SP sever, it keeps on prompting for authentication. I wish the installation of SharePoint could have taken care off. 

Anyways, you can run this to apply the change on the SharePoint servers.

Run this power shell command


New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa -Name "DisableLoopbackCheck" -value "1" -PropertyType dword
 
You may have to restart the servers and will have run this from all of your SharePoint servers.

You can also navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa in registry and create the dword32 for DisableLoopbackCheck, modify the value to 1.

I would prefer to use Power Shell any given day.

  1. Stupid question but on the SharePoint server or the app server?

  7. This method should only be run on your test and dev servers. It is a security risk to do so on your production servers. The way to do this on production is to specify the host names which are able to access the app. This is detailed in KB896861
