remotecmd="notepad.exe"
username = "XXXr"
password = "XXXXXXX"
remotehostname = "XXXXXXXX"
args = 
[psexecloc, "-u", username, "-p", password, remotehostname,   remotecmd]

output = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE)

outstr=output.communicate()
stdoutstr = outstr[0]
stderrstr = outstr[1]

Just a cmd will popup for a ms, facing issue in this code please help

I think you cannot execute graphical applications using psexec. Have you tried cmd /c dir for instance? — Jean-François Fabre

@Jean-FrançoisFabre You can execute GUI with psexec. And does your remotehostname contains a `\\` (double backslash) as a prefix? it should — arieljannai

aah good lead. Can you print psexecloc from python? you need raw prefix or 4 antislashes else it fails. — Jean-François Fabre

Be aware that the syntax of PsExec for your needs is: psexec \\hostname -u user -p pass executable and if it's a GUI, add the -i flag.

From san's comment, it takes more time for the GUI executable to load, than a non-gui exe

So the following does work now that I've tested it:
The part that was missing is the backslashes before the hostname

import subprocess,time

psexecloc ="psexec.exe"
remotecmd="notepad.exe"
username = "XXXr"
password = "XXXXXXX"
remotehostname = "\\\\my-pc-name"
args = [psexecloc, "-i", "-u", username, "-p", password, remotehostname,   remotecmd]

output = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE)
time.sleep(30)
outstr=output.communicate()
stdoutstr = outstr[0]
stderrstr = outstr[1]
print ("Output Tuple: ",outstr)

Psexec is not invoking the notepad.exe in the target machine, but I could see Psexec process in the task manager..

Unfortunately I don't have any accessible remote to test it again at the moment. Have you checked after running psexec if notepad is running on the remote? (even if not visible). You could also open notepad from a simple batch file. You can mark psexec to copy the file and then execute it. Maybe it will behave different

no, notepad is not running in the target machine but I could see only psexec process running in the target machine.

Any help on this will be appreciated

please try to add an -i flag (it receives a session number)
