i have a website that uses basic authentication through Active Directory. everything works great, however, when an account is either locked or disabled, the user just keeps getting the pop up box, so they don't know what's going on. is it possible to somehow redirect them to a proper error page, or give some more detail? instead of just having the pop up box come up again and again and again..
I don't have the environment to test this right now, but I came across error page codes of which contain "401.1 - Logon failed". As long as you have above IIS7. From the home of IIS in IIS section choose Error Pages and set this code and path to the htm file.
Then try failing login again.
