Active Directory object reset upon reimage

-

i re-imaged few computers , reused same names without removing them ad first. group policies not being applied , think due not removing them ad, re-joining domain, placing them in proper ous'. there way reset computer accounts without removing them ad , re-joining domain?

reset secure channel using active directory users , computers snap-in
right-click computer, , click reset account
must rejoin computer domain, , restart computer
or
dsmod computer "computerdn" –reset
rejoin computer domain, , restart computer

netdom reset machinename /domain domainname /usero username /passwordo {password | *}
nltest /server:name /sc_reset:domain\servername
commands resets secure channel attempting reset password on both computer , domain, not require rejoining or rebooting. 

can use windows powershell active directory module reset computer account.
test-computersecurechannel –repair 

in case
after reinstalling operating system on workstation,  even though used same computer name new installation generates new sid.
