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..
You would need to create a DWORD registry key in the registry called DisableLoopbackCheck and set it to 1.
Follow these steps:
Click Start, click Run, type regedit, and then click OK
In Registry Editor, locate and then click the following registry key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Lsa
Right-click Lsa, point to New, and then click DWORD Value.
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, and then restart your computer.
