Psexec and PSEXESVC service

Hi, bildos.

You can't. See explanation below.

How psexec works:

Sample command:

psexec \\target -u adminuser -p passw some_executable

psexec connects to \\target and authenticates as adminuser.
If this does not work, psexec will show an error message and exit.
Next psexec copies psexesvc.exe to \\target\Admin$ and launches it as a temporary service.
If this does not work, psexec will show an error message and exit.
psexesvc on \\target launches some_executable.
psexec and psexesvc use pipes to handle keyboard input and screen output.
Once some_executable finishes, psexesvc will terminate, too, and remove itself from the services list.
psexec will exit.
(If you use psexec's -d option things work slightly differently, but the result will be the same.)

Summary
There is no way of using psexec to execute a command remotely without having the temporary service psexesvc. But psexesvc will disappear when no longer needed.

Correct.

In the rare case that this should not happen, then

• from the local machine try to stop and remove it using

  sc.exe \\target stop psexesvc sc.exe \\target delete psexesvc

• or logon to the target machine and launch
  

  sc.exe stop psexesvc sc.exe delete psexesvc
