First and foremost: replace your PDC with something more recent than
Windows 2000. Now. Windows 2000 reached End-of-Life this past July. You
do *not* want to run this in a production environment anymore.

That said, I don't see anything wrong in running DHCP on a DC, provided
you follow the suggestions in [1] (allow only secure dynamic updates and
create a dedicated account for DHCP DDNS updates). As for the rest, I'd
separate infrastructure services (AD, DNS, DHCP) from application
services like RDS in application mode. VPN endpoints I'd separate from
everything else.

If you intend to virtualize your DCs as well, read [2,3] before making
your final decision.
