Did basically the same on Windows 2008 and 2008 R2 just this morning with success.

I seem to recall maybe posting something like that--The Internet remembers all, so if you all say so, it must be true =) I'm not sure it works in the GUI since Win7 though, or on other "modern" Microsoft OSes. I know we used to use this method on XP, but I seem to recall trying it more recently and not having success (was forced to restart in between). -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Free, Bob Sent: Tuesday, March 18, 2014 11:38 AM To: [email protected] Subject: Re: [NTSysADM] Rejoin Computer to Domain Without Removing Similar discussion on activedir a couple years ago. Bonnie may have been involved, don't recall. I had this in my notes from one of the Brians "Login to the afflicted computer as a local admin, disjoin the domain--but enter bogus domain credentials, so the computer's domain account doesn't get whacked--don't reboot yet or fully leave the computer naming dialog, and then rejoin and reboot. Alternatively, skip moving it to a workgroup altogether and just change the domain from the NetBIOS name to the FQDN or vice versa. So, if your computer is in a domain called Company, just change the name to company.com, enter creds and done." Finally for fixing and more importantly, understanding, things like this there's always joe. http://blog.joeware.net/2012/06/05/2508/ -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ben Scott Sent: Monday, March 17, 2014 7:17 PM To: [email protected] Subject: [spam] [dkim-failure] Re: [NTSysADM] Rejoin Computer to Domain Without Removing On Mon, Mar 17, 2014 at 4:44 PM, Charles Sullivan <[email protected]> wrote: > Is there a way I can rejoin a computer to the domain without first > removing it? This would be for a scenario where the computer object > has been removed, or something similar to that. Procedure I use is: 1. Log on to computer as local admin 2. Tell computer to leave the domain 2a. Give it bogus credentials when it prompts for an account to connect to the domain with 2b. Don't reboot 3. Tell computer to join domain 3a. Give it proper credentials this time 3b. Reboot when prompted Item 2a is to prevent the computer from removing anything from Active Directory. That way, when you (re)join it, there's a greater chance that things will still be there. Item 2b is to prevent the computer from ever acting on the fact that it's not a domain member anymore (and uninstalling software, reversing Group Policy, screwing up permissions, etc.). One could unplug the network cable for step 2 instead, I suppose. Credit to Bonnie Miller for the idea. -- Ben PG&E is committed to protecting our customers' privacy.
