I've been using the AD authentication module successfully for about a month now but on the eve of launching my new intranet I have a problem.  All users, including myself, are being challenged when hitting the windowssignin.aspx page and it won't accept legit credentials.

I do have a module that checks the users login.  If it's not present, I redirect them to windowssignin.aspx and that logins them in and returns them to the home page.  This has been in placed for about a week with success.  Not sure if this is causing the issue but I found the AD authentication sporadic at times and wouldn't log in the user so that's why I do the redirect to windowssignin.aspx.

Does anyone know how I can correct this or figure out what happened?

Thanks,

Mark

Mike,

Thanks for the response.

I was offline for a while looking at this but the issue dissapeared. Later on in the evening I found out another website was down that runs on the same server and I assume it wasn't a DNN or authentication issue after all.

I'll keep an eye on it but I believe I'm fine now.

Thanks,
Mark
