computer accounts on domain controller

[Guest]

We have a windows 2000 domain at work. If we want to reformat and reinstall
windows on some machines and rejoin them back to the domain with the same
computer names, do we need to delete the old computer accounts on the domain
controller before we join them back to the domain? When you join a computer
to the domain, does it use the old computer account because it has the same
name or does it require a new account even though it has the same name?

You have to remove the previous reference to the machine as a reinstalled PC
has a different SID, then add it
to the domain, you can join it to the domain during the setup process,
providing you have a set of domain admin credentials

What happens if you did not delete the old computer accounts and then you
join the new computers with the same computer account names?

You must have the proper permission to join them back using the same name.
This means that the user who is trying to rejoin the computer to domain must
have the following permission on the computer account:
