Who are Users:S-1-5-21-103702995-260........" S-1-5-32-544, "S-1-5-4"
Who are the above users? I happened to be in my Microsoft Intellipoint properties and noticed all of these in the "Groups or Users" security settings. Each one has a very small bright red question mark in between the "user" avatar and the "S-1-****" users.
