Extending the AD schema for End-User Recovery RRS feed

  • Question

  • Once you have completed the extension process (successfully or NOT); can this process be reversed in the AD?  I have been told that these changes in the AD are not reversible but I find that hard to believe.

  • Hello,

    I am not aware of any way to reverse the changes.  I will research this and post my findings on this thread.

  • Hi Ronald,


    When you extend AD Schema this is typically a permanent move that you don’t roll back. Trying to roll back can cause you intermittent issues down the road. If you needed to roll back you would want to do a restore AD vs. trying to remove the changes. Link for backing up and restoring Active Directory:


    If you are wondering what DPM 2010 actually does when it extends your AD schema it adds classes and attributes to Active Directory to support end-user recovery here is a link to a list of the classes and attributes:

  • Hello Ronald,

    There is no documented way that I can find to rollback the changes once the schema has been been extended for EUR.  If this is something that you are leery in doing, then I'd suggest to set this up in a test lab and test things out before implementing it.  Usually a schema extension is a permanent change in AD.
