Executing commands remotely on Windows client computers

There are several ways to execute a command on remote computers. You can use PSExec.exe, Windows PowerShell PSRemoting, and any other freeware tool which supports executing a command remotely. Most of the Windows Administrators do not know that there is a built-in tool available, called WMIC, to execute “any” command on the remote computers. WMIC, known as “Windows Management Instrumentation Command-line” is a WMI scripting interface that allows you to access WMI data on local or remote computers from Command Prompt.

Let’s assume, you want to update Group Policy Settings on a remote computer by using GPUpdate.exe. If you need to update GPO settings for one computer, use this command:

WMIC /node:Computer_Name process call create “cmd.exe /c GPUpdate.exe”

Since WMIC does not support executing commands on multiple computers, you need to use FOR loop as shown in the below command:

FOR /F “Tokens=*” %L IN (Computers.TXT) DO WMIC /node:%L process call create “cmd.exe /c GPUpdate.exe”

You can replace “cmd.exe /c GPUpdate.exe” with a choice of your command. Here is an example of stopping a service on a remote computer:

WMIC /node:Computer_Name process call create “Net Stop service_name”
