Answer 1

You can use the Domain Users

<authorization>
  <allow roles="XYZ\Domain Users"/>
</authorization>

Answer 2

Try this one and also disable Anonymous Authentication and only enable Integrated Windows Auth.

`<authentication mode="Windows" />
   <authorization>
   <allow roles="XYZ\Domain Users" />
   <deny users="*" />
 </authorization>`
