Custom COMPUETR certificate template is not showing up

Hi,
I've created a certificate template based on default COMPUTER template
inside CA templates. When I try use that template in GPO autoenrollment
it is not showing up. why??

When I try to generate certificate on the CLIENT throug MMC, if I use
Win XP no problem. If I use Win 2K I can't see the computer template I
created, but I can see the default COMPUTER template. why??

This is really urgent. Any help is greatly appreciated.

Thanks,
Ramesh.
