  • Promoting a server

    Greetings,
    I have an older box running Windows Server Standard 2003R2 as the primary active domain controller for my network.

    I have another box (newer). It has Windows Server Standard 2008R2. I am going to wipe the server to bare metal and re-install 2008R2. When I do the install, I also want to make it a member server to the domain. The eventual goal is to make it the new primary and decomission the old box.

    1: Do I add a role on the 2008R2 box to make it a member server?
    2: When ready what is the sequence to promote the 2008r2 box and demote the old 2003r2 box ?

    This is a very small LAN, very small AD.

    thanks.

    Rough sequence:

    If 2008 server is already in the domain, remove it cleanly
    Rebuild 2008 Server
    Join to domain as usual (this is NOT a role)
    Add ADDS role
    Promote to a DC
    Confirm replication of AD database and Sysvol between 2003 and 2008R2 DCs
    Add DNS role and confirm replication of DNS database
    Add other roles from 2003DC if required
    Remove roles from 2003DC after they are confirmed to be transferred
    If only 2 DCs, unpromote 2003 - FSMOs will move themselves.
    If more DCs, manually move FSMOs then unpromote 2003 DC
    Remove 2003 member server (as it now is) from domain

      1. No. Add it to the domain using the settings in Server Manager.

      2. As per Tom's (Ossian) instructions.

            Re: Promoting a server

            If this is the first non-2003 server and If ADPrep has not been run, yes, else no

            No harm in running it anyway

              Sorry,
              but I am reading conflicting information. So, another question:
              do I have to copy the \sources\adprep folder from the 2008R2 install dvd to the 2003 AD server ?

              thanks.

                Have you already run ADPrep?? If not then follow this

                  1. domain master is a 2003R2 server 32bit
                  2. Server I want to make a member server, then eventually promote to domain master
                  is 2008R2 64bit

                  Took 2008R2 64bit install disk and put it in the 2003R2 server.
                  1. Logged into the 2003R2 server as domain admin
                  2. Launched cmd prompt with admin rights.
                  3. typed : g:\support\adprep\adprep32 /forestprep

                  system trundled away and eventually puked out the following error:
                  adprep was unable to check the forest update status.
                  adprep encountered a win32 error.
                  Error code: 0x3a Error message: The specified server cannot perform the requested operation.

                  The adprep.log did not show anything different.
                  Google was NOT my friend.

                  Note: The 2003R2 server does not have a lot of free disk space (3.7GB).

                  thanks for any ideas.

                    Double check
                    a) the account you are using has Schema Admin permissions and
                    b) the DC you are doing it on holds the Schema Master FSMO
                    Even if it is the only DC, prior changes may have left it not holding all the FSMOs, in which case you will need to clean up AD before proceeding ( "check FSMO holders" for more info)

                    Disk space should not be an issue if it is a few Gb

                      Re: Promoting a server

                      OK.
                      Update:
                      1. The schema master WAS a different machine. It was powered off. When we powered it on, it blew. It was old. It was non repairable. So.....I had to seize the role. This was successful.
                      2. Ran adprep and it was successful.

                      By successful I mean completes with happy messages.

                      on 2008r2 server added adds. When I try to promote, it complains that adprep needs run. Unsure of what to do since I ran adprep and it completed successfully.

                      Any ideas ?

                        Any roles missing from DC? If the Schema Master was one then you may be missing something else.
                        1 1 was a racehorse.
                        2 2 was 1 2.
                        1 1 1 1 race 1 day,
                        2 2 1 1 2

                            Check the ADPREP syntax here:
                            https://technet.microsoft.com/en-gb/.../cc731728.aspx

                            Which have you run?

                              solved.

                              1. had run adprep32.exe /forestprep but forgot to run adprep32.exe /domainprep after it.
                              2. Ran adprep32.3xe /domainprep successfully.
                              3. Successfully promoted to ad server.

                              thanks.
