Yesterday is mentioned the 3 installation guide for SharePoint Development server. The guys from Critical Path Training recommend to disable DisableLoopbackCheck. After a research i found out that you definitely want to do this if you plan to develop locally on the server image, meaning you install Visual Studio on the server and then connect with Remote Desktop Connection to develop within the SharePoint Image.
Check Microsoft KB# 896861 for further information's. If you develop on the SharePoint Server and you get this error message in the internet browser:
When you use the fully qualified domain name (FQDN) or a custom host header to browse a local Web site that is hosted on a computer that is running Microsoft Internet Information Services (IIS) 5.1 or a later version, you may receive an error message that resembles the following:
HTTP 401.1 - Unauthorized: Logon Failed
then this KB solves the problem. I am going to disable this in my registry as I am going to develop on my Server.
