wmi.x_access_denied:

Question

I have a python script which extracts the hardware info of all my windows workstation in my network (for saying let it be client machines)

aim: to extract the hardware information of all the windows machines on the network.

my setup:

• python version - 3.7x (32bit)
• using wmi library to get the hardware info like serial number, system name.
• client machine - 300+, under the same domain and same network(192.168.21.0 - 192.168.21.200).

the issue I faced: if I run my script with passing the remote IP address with local admin's credentials, actually how wmi library works.

Error :

Traceback (most recent call last):
  File "C:\Python3\lib\site-packages\wmi.py", line 1263, in connect       
    authentication_level=authentication_level
  File "C:\Python3\lib\site-packages\wmi.py", line 1397, in connect_server

pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'SWbemLocator', 'Access is denied. ', None, 0, -2147024891), None)

During handling of the above exception, another exception occurred:

    con = wmi.WMI("192.168.225.117",user=r'admin',password='admin01')   #FILL WITH THE REMOTE MACHINE NAME

This wmi.x_access_denied can be overcome by enabling/changing these settings in each and every client machines, for testing purpose I checked and it worked, FYI this solution was giver by this blog WMI "access denied" error for remote computer

1. Enabled Remote access for WMI user from WMI Control -> CIMV2

2. enabled remote WMI through the firewall: netsh firewall set service RemoteAdmin enable

3. changed DCOM Configuration in dcomcnfg for WMI user by give that account “Remote Activation” permission

I have 200+ clients, so I cant go and enable or change these settings manually for every node I have.

Is there any possible solution, like creating any domain user with wmi access or writing any group policy for all the domain computers?

My main goal: To extract hardware information like workstation serialNumber, workstation name, GPU name, Monitor serial number of remote machines (windows 7 & 10) which resides in my same network.
