I am using Integrated Windows Authentication in my web application and only a few pages are restricted and needs to be authenticated. Now, what I am trying to implement is to redirect into another page when a usertry to open a restricted page and failed to authenticate through their domain user ID. I am a novice in this area. Can anyone help me in this please!

You must post this to the Windows Server 2003 or IIS Forums. This is related to IIS Custom Error, you cand customize the error going the the IIS Virtual Directory, there you will find custom error Tab (don't know exactly the tab name), there you can define. Normally this error is 404 error. hope this helps you.

Besides,you can refer to the article: http://blogs.msdn.com/david.wang/archive/2005/08/01/HOWTO_Common_URL_Redirection_Techniques_for_IIS_Summary.aspx

I guess, I am aware of this, but I never thought that this could be the trick. Thanks anyways, your suggestionwas helpful to me! And sorry about posting in the wrong Forum, I was having difficulties in finding the right Forum and just posted in the first available one.
