I have a machine that was a domain controller and everything else, includin an IIS site. I built new 2 new domain controllers and transferred the FSMO roles and waited a day and then demoted the original domain controller. Now the IIS site says :
HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers.
I have a call in with the web app vendor, but maybe someone can guess what I need to fix now. I haven't looked at IIS since this was installed and am pretty lost.
I thought about restoring the machine from a backup, but I think that would be an Active Directory disaster, right?
The server is Windows 2008 (not R2). The new DCs are 2008 R2
