I believe IE has some hardcoded behavior that treats names differently
depending on whether it has dots or not. The thing that changed is probably
its authentication/auto-logon behavior.
As to how it affects usage of Integrated Authentication -- maybe IE has code
in it that thinks "Integrated Authentication should not work over the
Internet" (because it usually does not). Sorry, dunno much more about IE
other than superficial observations of IE behavior from the outside.

So I've tried adding the host with domain specification inside Trusted Sites Security Zone and now my asp page works properly. I've found the solution but I can't understand the reason, or better, I couldn't found which option inside Security Option panel has solved my problem. Any idea ?
