In this guide, I will be showing you how to fix “the following error occurred attempting to rename the computer Account already exists”. An Active Directory (AD) domain is basically the same as an Internet domain. It “defines a realm of administrative autonomy, authority, and control” for a group of computers. Please how to fix “The logon attempt failed for the remote desktop connection“, and how to fix “An Attempt Was Made to Reference a Token That Does Not Exist” in Windows 10.
For how to set up a domain, see the following Active Directory: How to Setup a Domain Controller. Also for how to add a second DC, see the following How to add a second Domain Controller. For how to join a PC to a Domain, see the following Domain Join: How to join a computer to the Domain.
Active Directory Domain names are controlled by the same set of rules and principles, that govern traditional Domain Name Systems (DNS). The domain-based network provides centralized administration for corporate networks from a centralized location and this enables users to access only the resources for which they have been granted access.

Error occurred while attempting to join the Domain
