Thanks, I was able to connect to the remote machine. However, how do

The docs for the WMI Registry provider are here:

and you probably want this:

With _winreg I could just do:
keyPath = _winreg.ConnectRegistry(r"\\" + ip_a,_winreg.HKEY_LOCAL_MACHINE)
try:
hKey = _winreg.OpenKey (keyPath,
r"SYSTEM\CurrentControlSet\services\Tcpip\Parameters", 0,
_winreg.KEY_READ)
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?
Certainly a consideration. Generally WMI isn't the fastest thing in the
world either to connect nor to query. I suspect a try/except with
_winreg is worth a go, falling through to WMI.
