To perform an offline domain join, you can use the djoin.exe utility, which is included with Windows Server and client operating systems. This tool allows you to create a computer account in Active Directory and generate a provisioning package that can be used to join the domain without direct network connectivity.

To change the domain of a Windows computer using the Command Prompt, you can use the netdom command if you have the Remote Server Administration Tools installed. The command syntax is as follows: netdom join <ComputerName> /domain:<NewDomainName> /userD:<DomainUser> /passwordD:* Replace <ComputerName> with your computer's name, <NewDomainName> with the domain you want to join, and <DomainUser> with a user account that has permission to join the domain. After executing the command, you will typically need to restart the computer for the changes to take effect.
