Ive found this very handy.. recently, 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.
Its a ‘feature’ on the server that you need to disable as a workaround.
Caution: Microsoft Best practices is out of scope in this article. Do your own research on this topic.
You would need to create a DWORD registry key in the registry called DisableLoopbackCheck and set it to 1.
Follow these steps:
Option 1: Add this registry entry by PowerShell
New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa -Name "DisableLoopbackCheck" -value "1" -PropertyType dword
Option 2: Add this registry entry manually
Click Start, click Run, type regedit, and then click OK
In Registry Editor, locate the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Right-click Lsa, point to New, and then click DWORD Value. (In Win 2008, its DWORD 32bit)
Type DisableLoopbackCheck, and then press ENTER.
Right-click DisableLoopbackCheck, and then click Modify.
In the Value data box, type 1 and then click OK.
Quit Registry Editor.
You may need to restart your server.

The way of doing this is in production is to use method 1 as per Microsoft’s article http://support.microsoft.com/kb/896861
However, I have had endless problems with getting method 2 to work. The solution for me was always to add the basic hostheader to the backconnectionhostnames reg key AND the FQDN i.e. hostheadername.domain.local (for example). I have foudn that a reboot is necessary, rather than just iisreset/noforce. Just using the basic hostheader name alone did not work.
Thanks. Use this to solve my issues with search crawling sharepoint sites as well as opening sites in Designer.
worked like a charm! Thank you
