How to inventory network equipment correctly?

Question

Computer networks

We need an inventory of all equipment, software over the network without any hassle.
I tried habrahabr.ru/post/138400 but there are many inconsistencies and inconsistencies (which version of Aida was used, the psexec example is not working (as a result, he wrote his own, it starts the process on a remote host but does nothing), etc.)
Tell me who uses what for inventory (preferably free software)
or share an article =)
many thanks in advance
PS Even started digging towards WMI

Answer 1

OCS Inventory + GLPI should be enough.

Answer 2

I looked at your offer 3vi1_0n3 (link habrahabr.ru/post/104141 ), but I don’t really want to install third-party software additionally.

Answer 3

Accounting and control of computers in the network ( site ). For free. Setting
example .
