Exception when running PSExec on remote computer

Question

Running this command

    $processesToSpawn = 3

    for($i= 1; $i -le $processesToSpawn; $i++){

        psexec \\computername -i 2 -u "username" -p "password" "c:\myapp.exe"
    }

Produces the following error

    psexec : 
At C:\mypsScript.ps1:75 char:13
+             psexec \\computername  -i 2 -u "username" -p " ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

It executes and runs the first iteration of the loop fine, and opens the program that i want in the RDP session, but fails immediately after the first iteration.

Edit: The is only happens in the IDE, running the script from a PS command line runs fine. So consider this question solved.

Additionally, i had to add the -d switch to the PSExec command (Don't wait for process to terminate (non-interactive).)

Answer 1

Probably, the problem is that psexec does not wait for your process/app to complete.

Could you try the following code to see if it works?

psexec \\computername -i 2 -u "username" -p "password" cmd.exe /c "c:\myapp.exe"

(see http://forum.sysinternals.com/psexec-finishes-before-child_topic27463.html)

Answer 2

I believe the PSEXEC call in your script needs to end with the /c, I use the script as below.

C:\PSTools\psexec /accepteula -u domain\user -p psexec \\10.0.0.xxx cmd.exe /c "E:\teste\psexec\xxxx.bat"

Hope this helps!
