When you have more than 2 AOS servers in your Axapta setup, you might experience the following problem: the online user form will only tell you whether the user displayed is currently working on the same AOS as you (then it will say "thin") or on another AOS (then it will say "NotAOS").
As long as you only have 2 AOS that's not a big problem, as "Thin" will mean the user is on the same AOS as you and "NotAOS" means he is on the other one.
But if you have 3 or 4 AOS, "NotAOS" will not tell you on which of the other AOS the user is working on.
So, here you can download a little project where one column is added to the online user form displaying the AOS setting of the user (including AOS cluster information):
