What is the solution to find the data where Altiris clients not installed
I think this is not possible because Altiris client fetch report after install install altiris client.
You can find manually Altiris Client Not installed system.
Altiris management Console ->Manage ->All Computers ->
Check Where is Managed Symble not showing it's system not reporting Altiris Client.
You may Export all System Report in AD and Compaire With Altiris Client install system
Thanks In Advance
What kind of data do you want to find?
