How to unjoin a domain?

By lmayeda ·
I moved a few PCs to a remote site w/ the expectation that the servers would move soon after. The PCs were still a part of the domain and continued to work w/o a domain controller. The 'soon' became later and then it was decided that the new site would have a new PDC/domain. What problems will I have when these PCs attempt to join the new domain. How can I 'unjoin' them from the old domain before joining them to the new domain? Member servers are still connected to the old domain. Can theybe changed to be part of a workgroup prior to joining the new domain?

They can and should be changed to be part of a workgroup, before rebooting and adding them to the new domain. You need local administrator rights to each pc.

You don't mention what operating system your are running on these PCs. The answer is really dependant on the operating system. If they are running WinNT/2K/XP, then Answer 1 is correct. If they are running Win9x/ME, then they really aren't joinedto the domain in the sense that NT-based systems are.

Member servers can be changed from domain to domain in the same way as Answer 1 describes.

As answer 2 says win9x/me doesn't need to be joined by domain, you just have to make sure that they have the name of the right domain in the domain properties. However there is no need to first join a workgroup and then a domain, you can just join the new domain and everything should work fine.
One thing that both (answer 1 and 2) forgot to mention is that you should make sure on the old domain you delete the old computers from the domain. Otherwise you will have a lot of garbage on your old domain.

Win9x clients: Win9x offers no real security, so you can join-disjoin domains as you see fit. To disjoin, left-click Network Neighborhood, select the configuration tab, select your client for Microsoft Networks, click properties. Here you can specify whether this computer is logging into a Domain, and the name of the domain. On the server side, there is nothing to be done, as Win9x does not create computer accounts within the domain.

For NT-based clients: (NT/2000/XP), there are computerSID accounts which are created on the server (active directory for 2000 domains). Good housekeeping would warrant removing those accounts when they are no longer used. Keep in mind that simply by disjoining the domain the computer account is unusable. Once you have disjoined a domain, and should you later decide to rejoin that same domain with that same computer, a new computer account must be generated. Two ways of doing this are for either the administrator to create the account on the domain in advance of the valid user logging in, or for a domain administrator to log into the domain from the client, supplying her credentials when joining (domain computer account is created at this time). BTW, on 2000/XP you'll find the computer name via properties of My computer, and from here you can also select to join a domain .. etc.

All three of the above answers were fine, just thought I'd add some detail in case you were looking for more information.

You don't mention whether the remote site is linked to the orginal domain's site or not. If it is why not just place a bdc on this remote site to handle their logins and security.

If not all of the other answers would be correct, their really isn't a need to unjoin since you can just join the new domain.
