Override SCCM Reboot Time

The SCCM reboot counter is controled via the SCNotification application and Policy.  Below is a basic policy as seen from WbemTest and Policy Spy.

 

To modify this we create a local policy.  Local Policy will override the machine

WMIC /namespace:\\root\ccm\policy\machine\requestedconfig path CCM_RebootSettings Create PolicySource="local",PolicyVersion="1.0" ,SiteSettingsKey="1", RebootCountdown=259200, RebootCountDownFinalWindow=4400 /NOINTERACTIVE

When you run this command the policy looks like the one below

When the restart happens...

 

You have something like this above.



Once the machine is set to reboot the registry will change here
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Mobile Client\Reboot Management\RebootData

The OverrideRebootWindowTime is the Epoch time for the Forced box that cannot be closed to appear. 
Rebootby is the Epoch time that will cause the machine to restart.

I am still experimenting to see if the time can be modified as to cheat the reboot time and keep extending or to force it to be shorter.  I will detail those finding later. 

I did find the Epoch time had to be adjusted.  I found the time to subtract 5 hours to adjust for my Timezone,.  While it says it is in UTC I think it is UTC but offset from my timzone.  Odd.,  I might find the real solution once I delve deeper into this . 

System Center 2012 Configuration Manager Cmdlet Library has been released to Download Center

Do you want the PowerShell cmdlets but not the time to install the CU for them.  Well they are now a separate bundle that you can install. CUs will no longer have PowerShell updates packaged with them.


If you have R2, no matter what CU you have installed (or not installed) you can download this and update your environment.  RTM SP1 is NOT supported via this update.  You must be running the R2 platform to benefit from this change.




The download can be found here:

Information on the installation cmdlet Library is here: https://technet.microsoft.com/en-us/library/dn958404


Admins have been asking on how to update their environment in different steps and this is the answer from Microsoft to allow a quicker adoption of PowerShell and giving the customer the ability to control the CUs.

Have you ever wanted to have an odd Schedule or found that your site will not longer sync on the schedule but a full sync will work. 


Well here is some code to kick off a Full sync on your site.  All you have to do is create a scheduled task on the Central or primary site.
The code modifies the control file.  Because of some timing issues I did add a few seconds on to the request.

I know this works on SCCM 2007, I am sure it will work on SCCM 2012 but I never tried it:
