Problem executing a script on a remote host

[tester_V]

Greetings!

I have a remote host(windows) and a system(windows based) connected to it by a private network.
The host has Python 27 on it.
Once a day a Python script runs (scheduled run) on it,
It is mapping the system C: drive as an A: drive and copies files to the host from some directory,
also it does some other stuff. It runs fine, no problems.

I wanted to run the script on the host remotely from my server (windows, with Python 3.9) instead of running it from the Windows scheduler.

I found if I call the script it runs (does some other stuff) but it does not copy files.
No errors. When I run manually it does everything, including copying files.
Any idea who to fix this?
Here is a script to execute a script on a remote host:

import wmi
from socket import *
ip = 'xx.x.xxx.x'
username = 'user'
password = 'pass'

try:
    print("Establishing connection to %s" %ip)
    connection = wmi.WMI(ip, user=username, password=password)
    print("Connection established")
    connection.Win32_Process.Create(CommandLine=r"C:\Python27\python.exe C:\02\SubPrOc-Get-L_TESTING.py")
except wmi.x_wmi:
    print("Your Username and Password of "+getfqdn(ip)+" are wrong.")
exit   

Thank you.
