DNS/WINS/DHCP in NT environment

I have a Win NT based network comprising of 3 Win NT servers and a Win 2000
server. Its a flat network without any routers. Both the PDC and BDC are Win
NT servers. We have about 70 Win 2000 and Win 98 workstations. I am
interested in configuringa WINS/DNS/DHCP server into the network.
Currently, none of these services are running on the network. Is it possible
to bring in a Win 2000 server and configurte it with these services? Is it a
good idea to configure these services on Win 2000 instead of Win NT? Is
running these three services on one server, OK? What would the pro’s and
con’s be for running these services on Win 2000 compared to running them on
Win NT?

Thanks for the help!
