When you try to access the Server from localhost by it’s FQDN or CNAME repeatedly pops up for cridentials

February 24, 2010

This is about the folowing situation. I have one vitual PC for testing purposes. For example the machine is called Server01.domain.local. I have one local site hosted on it . A simple site writted on ASP.Net or Sharepoint site. It doesn’t matter. It has windows integrated authentication. I have a host header for example mysite.somedomain.com. It works perfectly from Internet. I have the host header name in local hosts file too. When i tried to browse that from local machine (mysite.somedomain.com) it pops up repeatedly for cridentials.

This happened with IIS 6.0 in windows server 2003 with sp1 or sp2. In windows server 2008 the behaviour is the same.

The solution is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0

New multistring value called

BackConnectionHostNames

Right click modify and add host headers if there are more. In this cause i add

mysite.somedomain.com
