Domain Controlle renaming RRS feed

  • Question

  • I am transitioning from two 2003 Active Directory servers to two new 2008 R2 Active Directory servers.  After transitioning all the FSMO roles to one of the new 2008 AD servers and dcpromo the old 2003 servers I have been asked to rename the two new 2008 AD servers to the names that the 2003 servers had.  I had planed to re-ip them to what the old servers had but my understanding is is not best pratice to reuse the names that the former 2003 servers had.  Can you tell me if Microsoft supports this and if so what would be the procedure to do this.  I have found documentation for renaming domain controllers to different names but nothing about renaming to a name of a demoted AD server.

  • Renaming to a demoted server is just fine as long as the old server is gone.  Since you have two dc's you may want to just demote, rename and promote.  That might be easier for you, but renaming works.

    If it were up to me I would demote/promote.

  • Since, you have already promoted one of the windows 2008 server to DC, you have to take route of renaming a domain controller, but for other windows 2003, demote the DC, wait for replication cycle & make sure, there is no references left & configure new windows 2008 R2 DC with new name.

    Changing the IP of the domain controller is well described in below articles. For renaming the domain controller, i would suggest use NTDSUTIL tool instead of My computer API from below link.

    Yes, it is not best practice to rename a domain controller, since renaming a domain controller doesn't update the FRS & DFSR replication member object, it has to be done manually.

    I would suggest, test the solution domain rename in a lab first.

  • You can reuse the name again for your new DC.  Make sure this name is not in AD database or in DNS/WINS etc. 

    Since you are planning to remove all Windows 2003 DCs, it is cleaner (and less admin work) to install the DC with correct name first. 

    Demote old DC1, make sure no reference in AD or DNS/WINS etc.  Install a windows 2008 server with this name and preform DCPROMO.  Transfer the FSMO role to new DC.  Repeat the same step on old DC2.

  • Hi,

    Demote 2003 DC1 and wait for some time for the replication to happen. Make sure that there is no references in AD/DNS/WINS. 

    Promote the 2008 DC with the old demoted server name (2003 DC1).
