I am adding a new web application to an existing IIS7 server (Windows 2008) and want to create a new app pool for it. However, when I do this, I keep getting the IE pop up asking for credentials when hitting the page remotely; locally it works. When I move the app to an old app pool, it works fine remotely and locally. Both old and new app pools are configured the same way. Both set to .net v2 and integrated managed pipeline mode and to use ApplicationPoolIdentity. When it fails, I see 401 1 2148074254 202 error in IIS logs. Any thoughts?
Thanks very much!
