MDT 2012 Update 1 Bug

Update: This bug has been fixed with the version of MDT 2012 Update 1 that is currently available for download. Update was released on 9/19/2012.

I came across a bug in MDT 2012 Update 1 today. This has been previously reported to the MDT team. They are able to reproduce it and are working on a solution. Here are the details:


  • Configuration Manager 2012 installed.
  • Configuration Manager 2012 Cumulative Update 1 applied.
  • MDT 2012 Update 1 installed.
  • MDT/Configuration Manager integration performed.
  • Attempted to create an MDT Task Sequence which failed with the following error:

Microsoft.ConfigurationManagement.ManagementProvider.SmsConnectionException: Failed to validate property

The recommendation from the forums is to roll back to MDT 2012. I have confirmed that this does in fact allow you to create an MDT integrated task sequence.
