Script for adding virtual desktops to the domain.

In creating a vmware view pool on 4.6, i am creating customization spec, for the pool, and in the run once, step i want to add a script which will add this virtual desktop to our domain based on a template which is already on the domain,

Is there any scripts i can use which will add the computer account to the domain and add it in a specific OU.   Possibly based on powershell.

Has anyone done a script which works, can anyone provide me one.

Thanks
