Thanks, I was able to connect to the remote machine. However, how do
I query for a very specific key value? I have to scan hundreds of
machines and need want to reduce what I am querying. I would like to
be able to scan a very specific key and report on its value.
With _winreg I could just do:
keyPath = _winreg.ConnectRegistry(r"\\" + ip_a,_winreg.HKEY_LOCAL_MACHINE)
hKey = _winreg.OpenKey (keyPath,
value,type = _winreg.QueryValueEx(hKey,"Domain")
Also, is there a performance hit with WMI where perhaps I want to try
to connect with the inherited credentials using _winreg first and then
use the MWI if that fails?
Thanks for your help!
