SharePoint site is prompting credentials Constantly or Disable the Loop back check

I was working on a server and we were trying to access the local SharePoint site http://127.0.0.1 or http://nameoflocalserver/pages/default.aspx and I was constantly prompted for the username and password. In SharePoint 2010, it can really annoy you by not accepting your username password credentials in the popup window.

·         It’s a ‘feature’ on the server that you need to disable as a workaround :

·         Note: Microsoft Best practices is out of scope in this article.

There are two methods to do this:

1.    Specify the host names in the registry -: BackConnectionHostNames (more secure and recommended for PRODUCTION servers). 

                  Refer http://support.microsoft.com/kb/896861

2.    Disable the loopback check - DisableLoopbackCheck (less secure and recommended for DEVELOPMENT environments). Read on to use this method 2 and add via an easy power shell cmd.

You would need to create a DWORD registry key in the registry Called DisableLoopbackCheck and set it to 1.

Follow the below steps to Disable Loopback check:

1.    Click Start, click Run, type regedit, and then click OK

2.    In Registry Editor, locate the following registry key:

3.    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

4.    Right-click Lsa, point to New, and then click DWORD Value. (In Win 2008, its DWORD 32bit)

5.    Type DisableLoopbackCheck, and then press ENTER.

6.    Right-click DisableLoopbackCheck, and then click Modify.

7.    In the Value data box, type 1 and then click OK.

8.    Quit Registry Editor.

Note: You may need to restart your server.
