DFS Namespace failure

I ran into a hard to find but easy to fix issue today on a Windows 2008 R2 DFS server, the namespace suddenly lost all folder targets and displayed as an empty folder. The eventlog showed the following:

 

Event ID 14534, source DfsSvc: DFS Root xxxxxĀ failed during initialization. The root will not be available.

Additionally, event ID 14503 was logged for each folder target under this namespace.

Solution: remove the server from the namespace, delete the namespace folder on the physical disk and readd the server to the namespace.

Content validation issues in SCCM 2012

Sometimes, distribution points have packages in their WMI repository that don’t exist any longer on the site server. When the distribution point goes through a content validation cycle, it will fail and change its status to ‘Warning’.

The error you’ll see in the Distribution Point Configuration Status overview is “Failed to validate content hash”.

Then something along the lines of “Failed to retrieve the package list on the distribution point. Or the package list in content library doesn’t match the one in WMI. Review smsdpmon.log for more information about this failure.”

So far it all sounds easy, and when we look at smsdpmon.log we do indeed see an error, 0x80070002 and the package ID in question. When we look up the package ID on the site server, it doesn’t exist.

To delete this package from the WMI repository Continue reading Content validation issues in SCCM 2012
