Install the certificate of the enterprise root CA as trusted root CA certificate in whole domain

after first installing the server 2008 enterprise root CA, all clients automaticly got the CAs cert it their Trusted root Certs store.

i see new PCs are not getting this.

here i see that this work by default with GPO (is this the same with server 2008 CA ?)

is this automaticly created in the "default domain policy"?

and if i dont find it there (maybe deleted by mistake) can it be recreated by the following?
