Windows Command – How to Remove Computer from Non-Existent Domain

active-directorycommand-line-interfacewindows

I lost my domain controller machine, and then add new domain controller but with a new domain. How do I remove network machines from old domain using command line and add to new domain? Machines using Windows Server 2008 Core (command line only)

net computer \\name del

works only on domain controller.

sconfig

When I try to exit from old domain, console requests username and password for exit. I type it, and then get error "Could not connect to domain" (old domain controller not exists)

What to do?

Try netdom remove computername /Domain:domain /UserD:user /PasswordD:* /Force

Type netdom remove /? for the full command usage. The /Force option is what you're looking for. Per the help:

Forces the unjoin of the machine from the domain even if the domain is not found or does not contain the matching computer object.

To join the members to the new domain: netdom join computername /Domain:domain /UserD:user /PasswordD:*

Again type netdom join /? for help with the command usage.
