Yeah, demote the dog, if it doesn't go smoothly then run NTDSUTIL and the metadata cleanup options. (Plenty of KB articles on that) Then once all is gone re-install the DC and re-promote Ron Oglesby Senior Technical Architect Microsoft MVP, Windows Server RapidApp, Chicago Office 312.372.7188 Mobile 815.325.7618 email roglesby@xxxxxxxxxxxx -----Original Message----- From: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, July 21, 2004 8:08 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SV: OT: Replacing a DC with a new machine I have a dozen other DCs, this is simply a remote site one, it has no FSMO roles. Sounds like my original thought will work however, so I'll head that route. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Svein Arild Haugum Sent: Wednesday, July 21, 2004 8:58 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] SV: OT: Replacing a DC with a new machine Depends. Do you have a second DC? If so, you need to move all FSMO roles to that one, and the GC. Then you can dismount the old one, and rebuild the new one with DCPROMO. If you only have one server. You need to setup the new one. Run DCPROMO and join it to the domain. Then move the GC and FSMOs. Then demote the old one. Mvh Svein Arild _____ Fra: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sendt: 21. juli 2004 14:45 Til: thin@xxxxxxxxxxxxx Emne: [THIN] OT: Replacing a DC with a new machine I have to setup a temporary server at one office and it needs to be a domain controller. In a few weeks I'll have a permanent machine to replace this temporary with. I have some programs that map folders via UNC paths and it's easier from that standpoint to keep the temporary server name the same as the permanent one. However, I'm not sure if that's the best way to do it from a DC standpoint . I've yet to need to replace an existing AD DC with a new machine, so I'm not familiar with the process. Would it be as basic as demoting the temporary server, deleting it from AD Users/Computers and then putting in my new machine in place and running dcpromo on it?
