    I want to upgrade my server to another faster physical machine with
    completely different hardware. My current setup is 1 domain say and I
    have 2 DCs, DC-Main and DC-Backup. DC-Main is the first DC holding the 5
    FSMO roles and this is the machine that I want to replace.

    My Questions:
    1) Do I just DCpromo the new machine and transfer all the 5 FSMO roles to my
    new DC and the demote the "DC-MAIN" machine, or is this method wrong?

    2) Is there any way to name my new machine DC-MAIN as well? I want this to
    be as seemless as possible. (to do this im thinking of transfering the 5
    roles to DC-Backup, then demote DC-MAIN, and promote the NEW DC-MAIN and
    transfer the roles back).

    Someone please give me some input. This procedure is totally new to me.

    Thanks in Advance!

  2. #2 will work. Make sure DC-Backup is a GC and is running DNS.

  3. this works, planned like under item one. Please do not forget to export
    the EFS recovery agent certificate of the administrator before you
    "dcpromo" the server.
    Without this certificate you are not able to recover encrypted user files.

  4. Option 2 will do the trick. Also remember to mark the new DC as a GC again.

    This is a new one on me... How do I do this?

    Does backing up the System State accomplish this?

  6. On the first DC open the "Default Domain Policy". Navigate to:

    Computer Settings\Security Settings\Public Key Policy\EFS Recovery Agent

    there you should see the efs recovery agent certificate.
    Point to this certicate and click with the right mouse button.

    All Tasks -> Export

    You must export it twice. One for the public key and one for the private

    Excellent! How often should this be done? That is, how often does it change?
