SCCM Outage On-going: Workarounds and Solutions

We have fixed a number of issues with SCCM and now have some workarounds for others which are listed below.  We are continuing to work on an automated a fix to ensure all clients are fully operational again as soon as possible.

If you have client PCs with any of the following issues, and need them working ASAP, please try the relevant workaround described below:

Issue 1: SCCM clients were not authenticating. Software updates and advertised programs will not run.

Cause: Residual issue from certificate issues weeks ago where W7 clients now have 2 certificates. One should have been marked as revoked but wasn’t. The other was correct but failed to work.

Work around solution: Delete both certificates from the computer’s personal certificate store. Reboot to encourage a new certificate. Reboot to get SCCM client working again. We will continue to work on an automated solution.

a)       Go to StartRun, type mmc and press Enter.

b)       Go to FileAddRemove Snap-In Add. Highlight Certificates, click Add, select Computer Account, click Finish.

c)       Select Local Computer and click Finish.

d)       Close the Add Standalone Snap-In dialog box and click OK.

e)       Browse to Certificates Personal Certificates.

f)        Delete the certificates with the computer name in the issued to column.

Issue 2: OSD media gets an error retrieving policy: 0x80004005. Log says failed to get client identity.

Solution: We have created new boot media with a newer version of the latest certificate and all IT staff will need to update their boot media.  We have added this boot image to the Live Core Task Sequences, the Beta Task Sequence, and both live and beta templates only.

Issue 3: Multicast has not been working from SCCM-Distro1

Issue 4: Hardware inventory not working on most clients

3 and 4 Solved: The work we have done on the certificates and management point has solved these issues.  We removed any reference to Network Load Balancing (NLB) which we no longer use and created a new management point certificate. We now have multicast working from all distribution points. We have also eliminated a large number of other errors in the logs of the management point and sccm-dbase.

We apologise for any inconvenience caused and will update you again when there is further progress.

Kind Regards,

Planned Maintenance: SCCM unavailable Wed 29th May AM

An issue has been identified with multicast not running from sccm-distro1.  This has had no affect on multicasting the W7 images because of the redundancy available from other distribution points.

SCCM will be unavailable intermittently from 8:30 – 12:00 Wednesday 29th May to test a fix which can easily be rolled back if necessary.

We will let you know on the DMS Labs blog when the work is complete.

Kind Regards,

IT Services



Action Required: SCCM and images share clean up

This year IT Staff will be asked to distribute custom W7 images to SCCM-Distro1 and 2.

Images currently distributed from SCCM-Distro1 and 2 will have been created from the W7 core lab image 2011/12. These images will be automatically deleted from sccm-store, SCCM console and the distribution points on Tuesday 4th June 2013.

The 2012/13 W7 images which were held on SCCM-Distro5 and 6 will not be automatically deleted but must be cleared out where possible. This is to make sure there will be enough space for this summer’s images and applications.

Action Required:

  • Please let us know via a Service Now Case if you need to keep any of the 2011/12 images on SCCM-Distro 1 & 2 (for example if this is still your most recent live image for your lab).
  • For images from last year (distributed on distro 5 and 6): Please delete SCCM image packages, associated task sequences, adverts and source files on sccm-store from last year if no longer required.
  • Please distribute this years custom W7 images to SCCM-Distro1 and 2.

Kind Regards,

IT Services
