  • You need to be Schema Admin in order to make changes at the Schema..

    It is not a common permission.. either Enterprise admin and Domain admin are not in this group.. so check that for a start.

    This is a forum strictly related to SysInternals Tools questions.

    Microsoft has moved all the old version of the forums to a new site called "Microsoft Q&A": Microsoft Q&A supported products | Microsoft Docs

    Please visit that site and post your question to the rigth forum.

    Thanks for your cooperation!

  • Update-AdmPwdADSchema updates the schema and adds two attributes.
    Make sure that the schema master is reachable and all required ports are opened. 
    And the user who is running the command should be a schema admin
