Win2k DHCP and router DHCP question

[groovin]

Im setting up a test server right now. I was wondering how win2k DHCP coexists with a routers DHCP/NAT?

For example, the DHCP server on my network is a router which also does NAT. What would happen if I put a Win2k DHCP server on the network as well? This machine would also be a domain controller. Where would the IP addresses come from? Would the Win2k server request IPs from the router and then assign them to workstations?

Im asking this because I eventually want to install Exchange 2000 on it for testing/educational purposes. I dont have many extra servers lying around so I would have to install DHCP, Exchange, and DNS on one machine (which is fine since this is only for testing).

Thanks

Two dhcp servers on one LAN is a big problem. Turn one or the other off, unless you want a bunch of interesting errors and wierdness.

DHCP servers dont interact well at all, neither will get addresses from each other, I would turn dhcp off on the router entirely, W2K server's dhcp will work much better than the routers will, and you can push all sorts of extra info to your clients, like wins server addresses, just make sure the router has the first address in the subnet and that you exclude a series of addresses for your gateway and server. you want those things static, esp. an active directory dc.

how would NAT work then? i only have one public IP available...

The router gets the public IP. The router is the gateway. Turn off DHCP on the router. Enable routing services on Win2k server. The router gets 192.168.0.1 The Server should get 192.168.0.2 and so on and so forth. You should be able to enable routing with the gateway being the router. I think

I was doing almost the same setup and canned the idea of using the router. I ran DSL to the Win2k machine at one nic and ran out to a switch with another. I used DHCP and Routing services and it works great. Do not use the standard Internet Connection Sharing. It will conflict (if it even lets you use it) with routing services. Internet connection sharing depends on DHCP from what I understand. If you enable Internet connection sharing you cannot use static IPs.

you can use staitc ips with ics enabled you just have to manually enter them, but putting 192.168.0.x as an ip and the default gateway as 192.168.0.1 and dns of 192.168.0.1 will work on all ics setups.

thanks for the replies...

how big of a network can win2k DHCP and routing services handle bandwidth-wise?? i know it depends largely on the hardware, but supposing your running a P3 based server with tons of RAM and intel NICs. i would think it can handle 50 users or so without too many problems.

I think you should learn the basics before learning Windows 2000 and Exchange 2000. Learn your network services and protocol's. This will build a good foundation for your more advanced education to sit on.

I've left my DHCP services on the router. I have a 2000 server box with DNS and IIS. I haven't experienced any problems, and I haven't had to mess with DHCP at home. Works out well.

ive been working with win2k for some time now, i just never worked with exchange besides managing email accounts. i think my basics are ok, not a pro of course otherwise i wouldnt be asking for opinions.
