But when i check the set as administrator check box for this user, i am able to login with Username: domain\username Password: pw

I came across similar issue for my one of my web app. If you are still facing this problem, you can fix this by going to Advanced Settings of the IIS App pool of your application and setting "Load User Profile" option to True.
