总结：修改SharePoint管理中心管理员密码后，新创建的站点拒绝访问
背景：
域用户作为管理中心的管理员，而域用户要定期更改密码，在创建新的Application时，出现Access Denied的问题。
After changing Domain user password, it is denied to access new application.
解决方案：
在注册表中添加：DisableLoopbackCheck
具体步骤：
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.
