DHCP & Router

[ALI7682]

I was wondering how I set up my router so that I can use Win2k Server as the DHCP server for my other computer but still allow both of the computers to share cable through the router?

Here is my opinion on DHCP.

While it is great in a large company with tens or hundreds of computers, it really isn't a necessity for someone with a internal network of 2-6 systems. I choose to use all static IPs because...

1. It is easy for me to know which computer has what IP address.

2. If I want to set up additional services that forward ports to certain IPs, then I can do so without having to worry about rebooting the system and getting a different IP.

3. It is more secure. I don't have to worry about someone spoofing my internal network and automatically getting a IP address.

Just my 2 cents on DHCP.

If you want to set it up though, you will have to enable DHCP on your Win2k server. Set up a scope and all the gateway and DNS settings. Then go to your client systems and set up to get a IP address from DHCP and use DHCP for WINS resolution and get use DHCP to get DNS info. You should be ready to rock and roll.

yes but how do i configure it so that my router still gives a dhcp to the server but not the client?

It isn't a good idea to run two DHCP services in your network. If you are going to run it from Windows 2000 server, then turn it off on the router and set up a static IP on the Win2k server. If you have two DHCP services running, your nic card will authenticate and get a IP address from the one that responds the quickest. Not a good thing necessarially. 🙂

Go into your router and disable DHCP. Go into your Win2k server, give it a static IP on your network, DNS, and Gateway settings. Then you can enable DHCP server on your Win2k server and set it up.

All the clients will get DHCP from the server then. 🙂

I know that this isn't answering your question, but a. why not just use the router as a DHCP server and b.why not use rras on win2k server to share the internet?

a. On a small network, I don't like to use DHCP. DHCP was meant to be used in companies with hundreds of computers. For a small network at home, I would prefer static IPs over DHCP. I also know that if someone is able to hack in and spoof your network, DHCP on the router would give the intruder a IP address automatically. It is a pretty remote possibility, but I still don't see the need to run it on the router. You CAN run DHCP on the router and many people do, however call it a personal preference of mine to not run it.

b. I don't use rras on Win2k for internet sharing...never have used it. I would much rather purchase a router for $75 and share the internet like that. It is faster, more stable, and not dependent on one system. I used to run Wingate on my server at home and share the internet like that. The only problem was when I rebooted, all computers on the network lost internet connection. I also had a problem when I would play internet games because of ports not being open and so on. A hardware router/firewall does all that and you pay less for it than the software costs.

Nightfall, I wasn't asking you. I was asking ALI why, if he was going to go ahead and use DHCP, why he wanted both a Win2k DHCP server, and a router that would do it for him. Why not just use one box or the other?

Just for testing/certification purposes and to have the knowledge of how to do it if it came about, i've figured it all out since the last post and thank you guys for helping earlier.
