Why won't WindowsPrincipal show as IUSR_<machine> ?

    I have a test harness set up to explore some .Net security stuff.
    I have an .aspx page w/ .cs code-behind that gets the current Windows identity of the asp.net thread:
    -=-=
    WindowsIdentity MyIdentity = WindowsIdentity.GetCurrent();
    WindowsPrincipal MyPrincipal = new WindowsPrincipal(MyIdentity);
    string Name = MyPrincipal.Identity.Name;
    string Type = MyPrincipal.Identity.AuthenticationType;
    string Auth = MyPrincipal.Identity.IsAuthenticated.ToString();
    //Identity values.
    string IdentName = MyIdentity.Name;
    string IdentType = MyIdentity.AuthenticationType;
    string IdentIsAuth = MyIdentity.IsAuthenticated.ToString();
    string ISAnon = MyIdentity.IsAnonymous.ToString();
    -=-=

    When I have IIS Security set to [anon + integrated security], my test page printed out:
    Principal Name: MYMACHINE\ASPNET
    Principal Type: NTLM
    Principal IsAuthenticated: True
    Identity IsAnonymous: False
    Identity IsGuest: False
    Identity IsSystem: False

    This is good.
    But when I removed integrated security from IIS Security tab my test page still prints out exactly the same thing! Then I remembered asp.net has it's own stuff in web.config, so I changed:
     <authentication mode="Windows" />
    to
     <authentication mode="None" />

    I still get exactly the same output from my test page! Just in case there's some weird caching going on here, I shut down my web server and ran IISRESET - still to no avail.

    I can sort of understand the PrincipalName=ASPNET (even though I would expect it to be IUSR_MYMACHINE). But I don't understand why it insists on having IsAuthenticated=True and IsAnonymous=False.
