prestaging computers in active directory

have set up a wds sysprep image which i am wanting to give a unique name to according to organisation standards. this computer then needs to be put in a specific active directory ou. it is to time consuming to run sysprep each time for the computers and so need to automate the process. so am wondering how do i prestage the computer in active directory in the required ou and allow it to be found during the setup process since the computer is automatically being put onto the domain.
