RE: Alert when a new PC joins the domain

[Ken Schaefer <Ken () adOpenStatic com>]

In addition to alerting you may wish to consider:
a) redirecting the container that new computers get added to, to a dedicated OU
b) configure a GPO for that OU that either runs a Machine startup script or uses Software installation GPO to push down 
your agent

That way you, hopefully, will also get your agent autoinstalled onto machines joining the domain. For machines where 
you don't want the agent installed automatically (e.g. maybe some servers) you'd need to look at pre-creating the 
computer object in the destination OU, or moving the object prior to rebooting, or a WMI filter or something.

Cheers
Ken

Thanks to everybody for your answers,  we use Kaseya to manage workstations, Kaseya depends of installing an agent in 
each workstation/server.
That's how we manage our inventory.

The scenario is this:
A tech can join a computer to the domain without no problem, they have permissions to do so.

The problem is : sometimes the PC added doesn't have this Kaseya agent , so it is completely out of my control 
(inventory speaking) unless I do the manual cross checking which is very time consuming.

That's why I need to implement an alert to notify me every time a PC has been joined to the domain, If I found that PC 
within my Kaseya inventory fine if not at least I can determine to what client this PC belongs, and what tech was 
working on that PC.

I am talking approx. 20 domains here.
Maybe this is not the right approach to the problem... I will be glad to hear other points of view.
