samba - Aug 2005 - How to re-add windows systems to domain

Hey all,

I just had to rebuild a Mac OS X 10.4.2 Open Directory Master and PDC  
- all of the windows computer records are gone now. Is there a way to  
re-add the servers to the PDC so that I don't have to touch each  
desktop to switch them to a local workgroup and then back to the  
domain? Or, is there some client side app I can run as a local  
desktop administrator which would repair the binding?

Thanks,

Dave
