System Center 2012 Configuration Manager : Troubleshooting and Resolving Content Mismatch Warnings on a Distribution Point with Powershell

You might see content mismatch warnings in System Center 2012 Configuration Manager when content validation runs and determines that there is a discrepancy between the expected list of packages in WMI on the distribution point and the packages in the content library as shown in the screenshot below.

You can see an example of this scenario in the following screenshot where a distribution point has a Warning state and there is a status message in the Details tab in the Details pane that shows there was a failure to retrieve the package list.


How to detect it and how to fix it manually is described here in the following article :

BUT , that is all manual work , and we hate that , don’t we Smile with tongue out . Doing this on around 35 Distribution points by hand isn’t an easy solution. Luckily we have an excellent PowerShell scripter in our team and all credits for creating this script goes to  Bart Serneels. He has written a PowerShell script to do all the work . He was happy to share this with you guys on the Technet Gallery.

As the package is not on the site and you must remove the package from WMI on the distribution point. The namespace to connect to is root\sccmdp. The class that contains the list of packages expected is SMS_PackagesInContLib.

Bart Serneels made a script to automate the removal of the invalid instances (those of which the package does not exist in the console anymore) in WMI on all distribution points. You can download it from

Multicast-enabled Distribution Points Stop Working after Upgrading to System Center 2012 R2 Configuration Manager

11:23 am in CM12, CM12 R2, ConfigMgr 2012, configmgr 2012 R2, ConfigMgr 2012 SP1, multicast, R2 by Kenny Buntinx [MVP]


If you upgrade your hierarchy  to System Center 2012 R2 Configuration Manager and you have distribution points that are enabled for multicast stop working, look for entries similar to the following in the mcsexec.log: Error finding namespace: 0xc1210106

Make sure that before you upgrade the site or hierarchy, to make sure that Cumulative Update 3 or later is installed.

However, if you have already upgraded the site to System Center 2012 R2 Configuration Manager and multicast is not working on distribution points, perform the following procedure on each distribution point that is enabled for multicast:

  1. Edit the properties of the distribution point, and click the Multicast tab.
  2. Clear the Enable multicast to simultaneously send data to multiple clients option, and click Apply.
  3. Wait for the multicast configuration to be removed from the distribution point. You can verify removal by checking the MCSSetup.log file.
  4. Select the Enable multicast to simultaneously send data to multiple clients option, and click OK.
  5. Wait for at least one hour to make sure that Hierarchy Manager has reinstalled the multicast server.

Hope it Helps ,
