Download Install SCCM ConfigMgr 2012 R2 CU3 and Stop MP Rotation plus Partial WSUS Sync Issue


Microsoft has released SCCM ConfigMgr 2012 R2 CU3 update. This Cumulative Update is something special. Don’t miss this out. SCCM 2012 MP rotation issue has been a big headache for loads of folks like me. SCCM 2012 R2 CU3 comes with a workaround for MP Rotation issue.  More details about MP rotation issue in SCCM 2012 “Workaround for Untrusted Forest SCCM 2012 MP Rotation Issue“. Microsoft introduced a registry key called “AllowedMPs” with this registry key you can force the client to communicate with specific MP which you’ve mentioned in the value of the registry key “AllowedMPs“. You can set FQDN of the MP which your client/s want to communicate.

Another update in ConfigMgr / SCCM 2012 R2 CU3 is related to software update sync. Microsoft has introduced registry key workaround to avoid Partial Software update Sync of child primary sites or secondary sites. There are some cases when your SCCM 2012 R2 CAS or primary site is under heavy load then the Child sites may perform partial WSUS synchronization. To avoid this you can set value for the registry key called “SyncGracePeriod“. This grace period will help to avoid partial software update sync scenarios in your environment. Maximum grace period allowed is 10 minutes.

Also, ConfigMgr SCCM 2012 R2 CU3 has included support for another list of non windows operating systems for application and package deployment. Installation of the CM 12 R2 CU3 is very straight forward. Log file related to installation is located at Windows/Temp/cm12-r2cu3-kb2994331-x64-enu.log and cm12-r2cu3-kb2994331-x64-enu.msi.log. Installation related errors can be reviewed from these logs. SCCM 2012 R2 CU3 admin console update related log file is configmgr2012adminui-r2-kb2994331-i386.msp.log.

In this post, I’m going to provide details about two workarounds provided by Microsoft.

2. How to set registry key to stop SCCM ConfigMgr 2012 Partial Software Update Sync Issue?

How to set registry key to stop SCCM ConfigMgr 2012 MP rotation Issue?

1. Install SCCM 2012 R2 CU3 update on your site servers.

2. Install SCCM 2012 R2 CU3 on client machine

SCCM 2012 R2 CU3 Client version must be updated to 5.00.7958.1401

SCCM 2012 R2 CU32


CCM Framework = 5.00.7958.1401.

Compliance and Settings Management = 5.00.7958.1401.

Power Management = 5.00.7958.1401.

Remote Tool Management = 5.00.7958.1401.

Software Distribution Agent = 5.00.7958.1401.

Software Update Agent = 5.00.7958.1401.

Task Sequence Components = 5.00.7958.1401.

3. Navigate to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM . Create a REG_MULTI_SZ registry value named “AllowedMPs” . Add FQDN name of MP in the registry value as mentioned in the following picture. This registry entry would be very useful for the scenarios explained in the post “Workaround for Untrusted Forest SCCM 2012 MP Rotation Issue“.

The “AllowedMPs” entry will restrict which SCCM 2012 management point (MP) a client can communicate with. In the following example my client will only communicate with the MP FQDN provided in the value “ACNCPRI.ConfigMgr.COM”

SCCM 2012 R2 CU3-3

Lcoationservice.log will notify you about ignoring the rest of the MPs in the MPlist and accepting only one MP in AllowedMPs.
MP List is forced, ignoring MP ''
MP List is forced, ignoring MP ''
MP List is forced, ignoring MP ''

How to set registry key to stop SCCM ConfigMgr 2012 Partial Software Update Sync Issue?

1. Login to the top most site server in your SCCM ConfigMgr 2012 R2 hierarchy. It could be ConfigMgr 2012 CAS server or standalone ConfigMgr Primary Server.


3. Create New sub key SyncGracePeriod with REG_DWORD value 600 seconds (10 minutes).

The partial synchronization issue can occur when the WSUS Synchronization Manager component on a primary site begins synchronization before WSUS has completed processing all updates metadata. To prevent this scenario, the following registry subkey can be configured to use a new value in seconds:

  1. Hi Anoop,

    I am having standalone site with SCCM 2012 R2 (WINDOWS 2008 R2 standard SP1 Server OS), shall I go head for this CU3..

    Best Regards,


      • Hi Anoop,

        Install SCCM 2012 R2 CU3 on client machine

        I would like know that we need to install cu3 updates manually By Collation from package on all client systems &


        or it install automatically from sccm 2012 R2 to all clients

        Best Regards,


      • During the installation SCCM 2012 R2 CU3, it will ask for the creation of client installation package x64 and x86. You can use those packages to update the client systems automatically.


      • Hi Anoop,

        Thanks for support & Your feed back.

        (1) yes I agree that the package is created during installation. But read some forms we need to push By Collations not by

        If I go to administration–> site configuration –> sites in the home tab there is a button called Hierarchy settings, the last tab is about Automatic client Upgrade……?

        Fine now this not big issue , now My concern is

        (2)After upgrade to CU3 I found that My components status unknown & site system roles are fine. But My system logs are not

        updating & no logs error

        .As I read the some forms that after installation of CU1 also on sccm 2012 R2 COMPNNETS STATUS going to UNKNOWN,

        some comments mentioned that wait for more time it will be online. any Bugs on SCCM 2012 R2…?

        on My SCCM 2012 R2 after updates CU3 shows as components

        CCM Framework = 5.00.7958.1401.

        Compliance and Settings Management = 5.00.7958.1000.
        Power Management = 5.00.7958.1000.
        Remote Tool Management = 5.00.7958.1000.
        Software Distribution Agent = 5.00.7958.1000
        Software Update Agent = 5.00.7958.1000
        Task Sequence Components = 5.00.7958.1000

        I will wait till Sunday , otherwise I will revert back My Backup snapshot to SCCM 2012 R2

        Kindly Advise.

        Best Regards,


      • 1. Automatic Upgrade doesn’t work for CUs… It only works for SPs and R2, R3 etc.

        2. First step, I would look into is CU3 installation log files. That may give you some idea about the failures (if there is any).


    • Dear Anoop,

      No such any error on 2012 2 cu3 log file (configmgr2012adminui-r2-kb2994331-i386.msp.log)

      But you can find below this 3 Lines on Red Color

      Best Regards,


  2. Hello Anoop,
    We have on CAS and 10 primary and 20 secondary server, in one secondary server we are facing some MP issues regularly. If we are updating CU3, is it chance to overcome this MP issue? please suggest,


  3. @ Anoop and Abdul, this actually can’t be used to force clients to talk to specific management points in a secondary site. See my post here: for more information. Abdul, if your clients aren’t talking correctly to a secondary site’s MP as a proxy MP it’s likely an issue with your boundaries/boundary group for the secondary sites location. – Justin

    • Yes Justin . That is 100 % true. Great post !! Thank you for posting here. 🙂 In my blog post, I’ve not mentioned MP rotation on secondary sites.


  4. Anoop and Justin, I am getting an error like “Failed to get DP locations as the expected version from MP “”. Error 0x8000ffff “

  5. Hi Anoop. We make use of MP replica databases. Before installing CU3 do we first need to remove the Replication Publications and subscriptions? Just like it was needed with the upgrade to R2?

  6. Hi Anoop, this post is amazing, I just followed and updated my SCCM 2012 R2. Just a curious question, it showed (3) in registry key; and “About” was also showed Version 1401. But when I quickly checked on Site Properties, it still showed Version 1000. Is there anything that I might did wrongly? It would be great if you can help me to figure out. Cheers, Thanks you,

  7. Hi Anoop,

    In previous versions the -Id parameter was available for the cmdlet Get-CMSoftwareUpdate. Appears that it was removed in this version. Executing the command “Get-CMSoftwareUpdate -Id 1234” will either work and return nothing or throw an error that the parameter does not map. Check it and see. Unfortunately for me, I used this parameter in some scripts and now I have to figure out how to use description.


  8. I have a problem that there is no check boxes appears into the SUP Language properties , so if you open SCCM 2012 R2 console and go to Administration -> sites -> Settings -> Software Update Point -> Languages , it will appears blank no check boxes appears, anyone can help on this ?

  9. Hi Anoop,

    I need help on SCCM 2012 R2,
