Re-running a ConfigMgr Task Sequence on Multiple Computers

Recently I deployed a very simple task sequence to all our laptop computers which installs a new WiFi profile.  However, on viewing the deployment reports I noticed a number of machines where the deployment was stuck in either the ‘running’ state, or ‘failed’.  Although the deployment is set to ‘Re-run if failed previous attempt’ it seems the task sequence will not re-run automatically, only if a new schedule is created.  I wanted a quick and easy way to simply trigger the deployment again on all the computers that needed it, so I modified a script I use for re-running a task sequence to run against all computers in a csv.

Here is the script.  You need PS remoting active in your environment.  Simply add the location of the csv that contains the computernames you want to re-run the deployment on (no header required), and the name of the task sequence, and the script will do the rest.  It’s a little crude at the moment, but it works!  After running this, my compliance figures for the deployment were immediately boosted, and only a handful of machines remained that required individual troubleshooting 🙂

$ComputerNames = Get-Content -Path C:\Script_Files\WiFi_Profile_Failures.csv
$TaskSequenceName = "WiFi Profile"
