Use PSEXEC to Execute Remote Commands

There are many instances in managing a network when it becomes neccessary, or at least more convenient, to be able to execute commands on a remote computer without the overhead of launching a full-fledged Remote Desktop session.

Until PowerShell Remoting came along there wasn?t a native way to run remote commands from Windows, and even now PS Remoting isn?t exactly intuitive. That?s where PSEXEC comes in.

PSEXEC is a utility from a developer named Mark Russinovich and his company SysInternals (long since purchased by Microsoft) that allows you to execute commands on a remote system. All you need is File and Print Sharing enabled on the remote system, and of course the appropriate user permissions to execute the command.

Here?s a quick example. Let?s say I just want to open a command line to another computer:

psexec \workstation1 cmd

This will give me a command shell (or DOS prompt if you prefer) to the computer workrstation1. But that?s pretty simplistic. Let?s try a more complicated example.

I?ve written a batch file to deploy some software, and it looks a little something like this:

@REM InstallPanda.bat – Installs Panda Cloud Security Client@ECHO OFFECHO Installing Panda Cloud Security Client…msiexec \fileserverPandawaagent.msi /qnECHO Installation completed with error code %ERRORLEVEL%

To run my batch file on a remote computer using PSEXEC, I could use the following command:

psexec \workstation1 -c InstallPanda.bat

The first argument \workstation1, is the name of the computer on which the command should be executed. The second argument -c, specifies that the file should be copied to the remote computer and executed from there. Of course the final argument InstallPanda.bat is the command I want to execute.

But wait, there?s more! If I wanted to execute the command on multiple computers at once, I can add the names of those computers to a text file and call:

psexec @computerlist.txt -c InstallPanda.bat

I?ve been using this psexec commands just like this as a poor man?s software deployment too for years. To download PSEXEC and for a full run-down of PSEXEC?s parameters and features, visit the PSEXEC homepage on Microsoft.com.
