安装SharePoint2010的准备工作-3

You have two options for working with loopback checks, disabling or configuring. Disabling the loopback check increases your attack surface for security threats. As MS KB 896861 states, the loopback check "is designed to help prevent reflection attacks on your computer." 

Option 1 - Disabling

Run this PowerShell script by Michael Blumenthal

Restart your server

Option 2 - Configuring

The more secure option is to specify host names that you would like to allow connections to from the browser on your server.
