How does Active Scanning work?

[VOIN_Licensing]

Hi,

I am trying to understand how Active Scanning works in detail. The documentation states that it does the following:

"Lansweeper queries all domain controllers in the domain for newly logged on computers. This process is repeated every 15 minutes."

My question is: How exactly does it determine which computer has recently logged in? Is it reading an attribute from AD such as lastLogon?

Also, does it scan only the specified OU or also any sub OUs?

E.g, if I have the OUs
domain\MyComputers
domain\MyComputers\Loc1
domain\MyComputers\Loc2

and I tell it to scan domain\MyComputers, will it include objects from the Loc1 and Loc2 OUs?

Thanks.

Yes, it reads this from all domain controllers because the date is not replicated.

Also, does it scan only the specified OU or also any sub OUs?

E.g, if I have the OUs
domain\MyComputers
domain\MyComputers\Loc1
domain\MyComputers\Loc2

and I tell it to scan domain\MyComputers, will it include objects from the Loc1 and Loc2 OUs?

Both loc1 and loc2 will be scanned if you can domain\mycomputers.
Note that you need to enter the ou in adsi format: ou=mycomputers,dc=domain,dc=local
