To make your life easier, it's better to use a separate router to handle 
your new subnets.
So you don't need to change anything on your AD DC.
BTW, you have to have a router to do the routing.

You have to do routing between subnets either via a router or your AD DC.
I don't think it's a good idea using the AD DC as a router.
Does routing affect the file sharing?
