after demotion you still need to delete the server object manually in sites and services (this is normal) (everything else like computer account, frs stuff and ntds settings is removed by dcpromo) 1) you can promote servers to DCs while they are member of a domain or not. it does not matter. the only difference is during DCPROMO. if the server is already a member then that step is skipped 2) if the NTDS setting is still there the demotion was not successful. perform a metadata cleanup first before promoting the other server to a DC (http://blogs.dirteam.com/blogs/jorge/archive/2005/12/03/213.aspx) Met vriendelijke groeten / Kind regards, Ing.

________________________________ From: [EMAIL PROTECTED] on behalf of Al Lilianstrom Sent: Thu 2006-08-17 14:36 To: [email protected] Subject: [ActiveDir] w2k3 dcpromo failure We're in the process of replacing our w2k DCs with w2k3 machines. Forestprep and domainprep went fine as well as putting the first new w2k3 DC up. Yesterday we demoted one of the old w2k machines and removed it from the domain. Configured a w2k3 server with the same name and IP and ran dcpromo when it was a workgroup member. About 6 minutes into the process this event showed up in the directory service log ---- Event Type: Error Event Source: NTDS General Event Category: Internal Processing Event ID: 1168 Date: 8/16/2006 Time: 2:06:35 PM User: NT AUTHORITY\ANONYMOUS LOGON Computer: BIRD Description: Internal error: An Active Directory error has occurred. Additional Data Error value (decimal): -1073741823 Error value (hex): c0000001 Internal ID: 3000e54 and then this Event Type: Information Event Source: NTDS Setup Event Category: Setup Event ID: 1442 Date: 8/16/2006 Time: 2:06:57 PM User: N/A Computer: BIRD Description: During the cleanup operation of a failed Active Directory installation, the NTDS Settings object for the local server could not be deleted from the remote domain controller. Server: CN=BIRD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=wn,DC=fnal,DC=gov Remote domain controller: lbird.wn.fnal.gov User Action Delete this object manually using Active Directory Sites and Services. Additional Data Error value: The RPC server is unavailable. 1722 ---- The server ended up being non responsive and required a reboot. I've been doing some research and I can' find answers to a a couple of questions: 1) Would starting the dcpromo process with the server not in the domain have caused this? I've always added the machine to the domain before promotion. The admin who attempted the promotion said he has done it this way before. 2) When deleting the object from AD (as specified above) the option that actually deletes the object states that the DC is permanently offline and can no longer be demoted... Does chosing this option prevent me from adding the DC with the same name (Like seizing FSMO roles) ? al -- Al Lilianstrom CD/CSS/CSI [EMAIL PROTECTED] List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.activedir.org/ml/threads.aspx This e-mail and any attachment is for authorised use by the intended recipient(s) only.
