Unable to Browse to SharePoint Site from Server - Custom Host Header

I have created a web application with a custom host header and on the server, I am not able to browse to the site. The problem is the loopback check. To resolve this issue, I need to disable loopback check registry key.

1. Open the Registry Editor (regedit)
Caution: Incorrectly editing the registry can severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
2. Open the following key: HKLM\System\CurrentControlSet\Control\Lsa.
3. Create a new DWORD value called DisableLoopbackCheck.
4. Set the value to 1.
5. Reboot the server.
Note: This is required for the change to take effect.
If this resolves the issue, there is a more secure way of making this change. Instead of making the server-wide change that DisableLoopbackCheck implements, you can disable checking for specific host names. For more information about how to do this, see the following article in the Microsoft Knowledge Base
