RAS and DHCP

I am currently in the progress of upgrading my Windows NT
domain to Windows Server 2003. In an attempt to "do more
with less", I tried to get rid of my old clunky RAS
server and put all RRAS services on my 2K3 domain
controller that is also running the DHCP, WINS and DNS
services. I'd had this domain controller up and running
successfully for a little over a month before making it a
RRAS server. After loading the RRAS service, hooking up
my Digi and configuring my modems, I started receiving
complaints from users that could no longer receive an ip
address from DHCP. I manually assigned ip info on each
of the problem users until I finally put two and two
together and figured out that RRAS was probably causing
the problems. I stopped the RRRAS service on this server
and now DHCP is back to working again.

My questions are, can I successfully run RRAS and DHCP on
the same server, and if so, how in the heck do I
configure RRAS so that it does not interfere with normal
DHCP duties?

Thanks in advance for the help.

If RRAS is set to "obtain IP addresses automatically" it will lease IP
addresses from DHCP to use as its address pool. In some cases this may
deplete your DHCP scope.

There is a registry key which determines how many addresses RRAS will
lease at a time. Or you can configue RRAS to use a defined set of IPs, and
exclude those from your scope.

If you are short of IPs in your DHCP scope, you can use a different IP
subnet for your address pool, and route the remote subnet through the RRAS
server. (That is, you route all remote clients as if they were a remote
site).

Hmmm. I'm only using 20% of the available addresses in
this scope, so it looks like I have plenty to go around.
