I have a problem IIS 6 server that prompts domain users for login credentials by both machine name and IP address. If the user tries to login by machine name (http://machineName/Application) then IIS prompts the user but rejects the login credentials no matter what is entered. If the user tries to log in by ip address then they are prompted but if the credentials are correct then the login succeeds and the application is loaded.
I recently had to demote the master domain controller and re-promote it (don't ask...) and so I dropped all the servers from the old domain and re-added then to the new domain (of the same name) and they all work fine but this one IIS 6 web server.
I re-imaged the IIS 6.0 server from bare metal just to get past this problem but the new image is demonstrating the exact same issue!
Even when logged in locally to webserver1 I can't even get past the login prompts when trying to connect to http://webserver1/app
What am I missing?
