SCCM Client Not Updating the server - Part 2

Following on from this post the fix I decided to use is again, not ideal but it will get the machines talking back to the SCCM server.

The solution was to create a task sequence in Group Policy Preferences.
"Computer Configuration" > "Preferences" > "Control Panel Settings" > "Scheduled Tasks".

Create a new task with the following settings. The most important one is "Run with highest priviledges". Enter the details of an admin account that can run this on the PC's you want it to as well.

Create a new trigger, I went for "At log on", and delayed this by an hour. So after the user has been logged in for an hour, run this task. I also add a limit to how long this can run, just incase.

Create a new action, "Start a program". You want to run:

C:\Windows\System32\ccm\ccmrepair.exe

I have also added a condition that a network connection must be available. There is no point trying to reconnect to the server if it cannot be reached.

The rest of the settings dont really matter, but the above is what I went for. As long as a machine gets Group Policy, the SCCM client will repair.

Still best to resolve the issue with the build as outlined in this post, but this will fix the ones that slipped through the deployment.

SCCM Client Not Updating the server

PART 2, the more reliable solution

Post deployment clients are not talking to the SCCM server and updating it with their information.

The blog post here has some great information on how to solve the issue. What it doesnt cover is how to get the PC's you have rolled out already.

What J.C. Hornbeck does mention is where to correct it, the registry key:
HKLM\SOFTWARE\Microsoft\CCM\CcmExec\ProvisioningMode="true"

I have created a Group Policy Preference to change the "true" to a "false". Follow this up with the script from Microsoft here. If you are deploying this out there, comment all the "Echo" commands out so it gives no prompts and is 100% silent.

This is NOT a fix for the root issue, but gets the clients already deployed to comunicate back to the mothership
