Can I keep DNS and WINS on the PDC server?

I am running a flat Windows 2000 PDC server with Exchange 2000 on it. I have two other Win2000 servers in this domain and one NT 4.0 server. If all workstations are logging onto the Win2000 domain, do I need to run DNS and WINS on the PDC (primary domain controller) server, or can I run this on another box? What is recommended for best performance?
If you do not have too many servers and workstations (e.g., less than 1000) then leaving DNS and WINS on one of the DCs should be fine. Running the DNS and WINS on another machine will help offload some of the load from the Windows 2000 DCs, which will help performance of both the DNS and the DC -- but, again, if you do not have too many users and servers, it is more cost-effective to run all of the services on just a couple of machines.
