Remove Essentials role, any "essentials" limitations left?


  • Hello All,

    After three years of continuous (and loyal) service, i am thinking about reinstalling / rebuilding our Server 2012 Essentials Domain Controller. But as our company has grown, a fail-over cluster becomes a necessity. I already have a SRV 2012 standard as secondary domain controller. What i am planning to do is:

    1. Turn the Essentials server off, and remove it from the domain
    2. Promote the SRV 2012 Standard to "Full" DC, having all roles.
    3. Reinstall the Essentials server from scratch
    4. Remove the Essentials role from the essentials server, turning it into a "standard"-server
    5. Join the EX-essentials server to the domain and promote it to DC
    6. Configure failover clustering
    7. Go for coffee or a beer.

    Of course i am wondering:

    • Is this scenario a feasible one?
    • Will remove the Essentials role turn an essentials server into a "standard" SRV-2012, without any limitations regarding, especially, fail-over clustering?
    • Is there any other thing i am missing??

    Thanks for your swift reply!

  • I would do 2 before 1, much easier.

    If the server is the Essentials SKU version rather than Standard with Essentials Role, i would imagine this breaks the license in some way.

  • Hi,

    If it is Windows Server Essentials SKU (open run, type “msinfo32”, check OS name displayed in summary, it is Windows Server Essentials), Windows Server Essentials Experience server role is necessary and it cannot be changed to “standard” server.

    Besides, once WSE has been joined to domain, it must be PDC which holds all FSMO roles. At same time, user and device limitation is forced. Also, Windows Server Essentials does not support failover clustering.

    Based on your description, WSE does not meet your requirement due to company growing. As WSE is designed for small business environment with simple network, you may consider of demote and remove your WSE, and migrate the domain to Standard/Datacenter version.

  • Only Windows Server 2012 R2 and Windows Server 2016 offer the Windows Server Essentials Experience (WSEE) server role (in both the Standard and Datacenter editions). He states that he is using the older Windows Server 2012 Essentials edition, which is only available in the SKU form (i.e. the WSEE role is not available in Windows Server 2012 Standard).

    However, Windows Server 2012 Essentials can be "transitioned" into Windows Server 2012 Standard if one is willing to pay Microsoft for two licenses (i.e. pay them once for the Essentials SKU license and then pay them once again for the Standard license).

    Personally, I'd pay for a brand new Windows Server 2016 Standard license before I purchased another license for the old, and now outdated, Windows Server 2012 Standard.
