Guest Gerald Posted August 31, 2007 Posted August 31, 2007 I want to remove a 2nd Server 2003 off our domain to upgrades drives and install OS again. It is installed as a 2nd domain controller. How do i remove it successfuly and then return it again after the re-install process? Thanks in advance
Guest Meinolf Weber Posted August 31, 2007 Posted August 31, 2007 Re: Remove 2nd server off domain Hello Gerald, Move the 5 FSMO roles to the other DC. Make the staying DC Global catalog if not done. Check that DNS is installed as Active directory integrated zone and configure the clients to use the staying DNS server. If you use DHCP check that the second also is DHCP server with the right config for your environment. If everything is running, then you can demote the server with dcpromo and follow the wizard (read carefully). After the demotion shut it down and then you can delete the account from the domain. Because you make a new install a new SID will be created and even if you use the same name it will be identified as totally new DC in the domain. If you don't demote the server you will have a lot of replication errors in the event viewer.

Guest Gerald Posted August 31, 2007 Posted August 31, 2007 Re: Remove 2nd server off domain Hi Thanks ... The remaining server is the primary DC and also DHCP. The one been removed was brought in as a "secondary" DC. Does this matter?

Guest Meinolf Weber Posted August 31, 2007 Posted August 31, 2007 Re: Remove 2nd server off domain Hello Gerald, No, to be sure check the FSMO roles on the running machine and the Global catalog. Since Windows 2000 theire is no longer primary or secondary. The important part are the 5 FSMO roles and the Global catalog.
