Greetings everyone,

I have installed DNN as a new install on a Windows 2008 server platform. I have followed all of the instructions in setting up a new DNN instance as well as the instructions for getting the AD module working, and I'm having an issue.

The module is working, in that I can click on Login, click Windows Login, and use any Domain credential to log into the site. However, if I click on the link,
http://<DotNetNuke_Install>/DesktopModules/AuthenticationServices/Active Directory/WindowsSignin.aspx, I get a credentials box, but none of the supplied credentials work. After three attempts I get kicked out. The automatic login does not work either. My goal is to have the user automatically logged in with their AD account.

To summarize what I have checked and tried:

I have verified that the Application Pool is on Classic mode.
The Default Web Site's Authentication is set to Anonymous and Forms.
The DotNetNuke application itself is set to Anonymous and Forms
The WindowsSignin.aspx file is set to Windows Login.
The account associated with the application pool has full access to both the DNN directory and the Default Web Site directory.
I've done a few other things that slip my memory.

This is Windows 2008 Standard and IIS 7.5

I should also mention that previous to all this, it was stuck in an authentication loop, where it would continue to try and open the page. It seems strange that I am able to log on with any Windows account through the regular log on area, but not through the WindowsSignin.aspx form, or Automatically as is desired.

I appreciate any help you can offer. I'm totally lost.
