New Setup/config for server 2003 - Need help configuring DHCP 2

[TargaMike]

I am a beginner at this, and I am having some problems with WS 2003 DHCP at the moment.

My setup is simply the DSL modem which is setup in bridge mode, a 12 port switch, the server, 3 PC's and 4 Mac's.

I have 8 static IP addresses which I have manually assigned to the PC's and Mac's. However, with the new server and WS 2003 Enterprise OS, I want to use dynamic IP's assigned by our new server running Windows 2003 Enterprise.

I have the OS installed, along with a basic config, i.e. file server, print server, active folders, etc.

From this point on is where I get a lost. I know I want DHCP installed, but don't know exactly what my config settings should be, and whether I need to install DNS server and/or WINS server in order for the DHCP server to function. My hunch is that I need the DNS server, but not the WINS server installed, but like I said I am an IT rookie, and lack experience and knowledge Windows Server 2003, DHCP and DNS in general

I know this is basic stuff, and I thought I could muddle my way through it. So I installed DHCP and DNS servers, with the wizard, but it isn't working at all as far as I can tell since it doesn't assign IP addresses to the PC's or Mac's.

Please, is there anyone who is willing to help me out?

I have zero experience with setting up a server and network in general and DHCP, DNS, and Windows Server OS specifically, so please help me if you can and I hope you will have patience with my ignorance.


Cheers all!

the clue is in your third para you have asigned static ip addresses that is why you are not seeing ip asignment.

first ensure that the server is and has been set a static address. use the wizard to if you want dns/dhcp and AD ensure you point it to the servers static address.
turn off dhcp on the router/modem if running??

use statics for your printers and maybe a good script from here in the forum by markdmac (MVPs on the right of this page) ensure u point the Gateway to you internet provider.

ensure clients are dhcp clients reboot them and see if you pick up from the server addresses.. yes activate/authorise the scope on dhcp when it askes

there is a lot of answers if you search under dns/dhcp in this forum it will help.. and dont forget microsofts knowledge base...good luck!!!

Stand up wherever you are, go to the nearest window and yell as loud as you can, 'I'm mad as hell, and I'm not going to take it anymore.'

I don't see a firewall listed there, and the "I have 8 static IP addresses" makes me wonder if you're attempting to assign public IP addresses to internal network devices.

Thanks for the replies.

Once I had the DHCP server installed and configured, I switched the clients to "Obtain IP Adress Automatically", and then restarted them. Once restarted they would assign themselves IP's with Windows XP's APIPA self assigning function, i.e. the IP addresses started with 169.254. rather than the IP address from the range I specified which was 10.0.0.100 to 10.0.0.200

You are correct at this time there isn't a firewall present.

You might be correct, although I don't think that is the case. I didn't use any static IP's for any devices Other than for the network cards in the server. My servers configuration disk asked for the internet provider IP's, gateway, dns, etc. I used 2 static ip addresses here. 2 IP's since my server has dual Broadcom NetXtreme cards for load balancing. Otherwise I am not assigning any other static IP's. Was this incorrect? If so, how should the server be setup so that it can access the internet, and also allow the network clients to access the internet?


Also, I am reading through several reference sources and tutorials including Microsoft's knowledgebase, but if anyone knows of any other great Windows 2003 tutorials for beginners, I would really appreciate hearing about it.


Again, thanks for the help!

Like 58Sniper said that he doesnt see a firewall. Im sure he would say the same think im gonna say, and that is to get a firewall because just having the DSL modem plugged into the switch is not wise at all. You are just asking to be hacked if you have your network exposed like that. If you get a router/firewall then you can assign it one of those static ips for the dsl modem. Some routers like the symantec i use have DUAL WAN ports for load balancing and you can assign each wan port a static ip.

Your server(s) should be assigned a static ip(s) for your internal network, and not one of the static ips that came with the DSL modem. This is probably why your clients cant find your DHCP server is because you have the server nics assigned with the DSL ips.

If you have active directory installed then you should already have DNS installed and its probably wise to install WINS as well.

Heres an example of a server setup like i have mine. I replaced all the domain names with example.net as i used this since i have exchange installed. (So much easier for me)

IP: 10.25.18.10
SUBNET: 255.255.255.0
GATEWAY: 10.25.18.1
DNS 1: 10.25.18.10
DNS 2: 10.25.19.10
WINS: 10.25.48.10
DNS Suffix: example.net (or you can use example.local)

Heres an example of a DHCP Server Setup like i have mine...

Scope: 10.25.18.150 - 10.25.18.200
003 Router: 10.25.18.1
006 DNS: 10.25.18.10; 10.25.19.10
015 DNS Name: example.net
044 WINS/NBNS Server: 10.25.18.10
046 WINS/NBT Node Type: 0x8

And for all your clients that you will have static ips for make sure you give them an ip for your internal network. Just make sure it doesnt fall within the scope of your DHCP server.

Oh, and when you install DNS you need to make sure you list your ISPs DNS IPs in the fowarders so that the clients can access the internet.

pressed submit to early....


for the DNS names like i have listed... if you have active directory installed you use that DNS name that you used in AD. Say if you used mycompany.local or mycompany.org or something you would use that as your DNS Suffix. Since i have an exchange server as well i just went ahead and made my entire enterprise a .net dns suffix cause i was kinda lazy and didnt want to mess with anything in exchange. If you dont have active directory installed you really dont have to have a dns suffix.

always up for help myself!!! i was told by my masters in here with great knowledge if your not running pre xp machines you dont require wins server or there settings, just anothe 2 pennies worth.. some might argue differently

Stand up wherever you are, go to the nearest window and yell as loud as you can, 'I'm mad as hell, and I'm not going to take it anymore.'

Well, that's not absolutely true (about not needing WINS). In certain circumstances, WINS is still required, and it has to do with server apps more than clients. While it's UNLIKELY that it's needed here (especially in a non-routed network), it might still help.

TargaMike - if you're plugging the DSL directly into a switch or a server, without a firewall, you're asking for trouble. A LOT OF IT. Your network (and everything on it), will most certainly be under foreign control quite quickly.

Thanks everyone, I appreciate all the help. With all this info, I think I can get it set up properly. And I definately agree about the firewall, I actually had planned on getting a router installed for the security reasons alone. I will get it installed today, and then reconfigure my DNS, DHCP and WINS servers as suggested above.

Any recommendations on which brand of router to use? Are some more secure than others? Since I have a switch in place I don't need a lot of ports, just the WAN port and 2 LAN ports for the server. Not sure a dual WAN port router would do me any good since I only have one DSL modem-ISP connection.

Reynolwi, does the dual WAN port router require 2 DSL/internet connections for it to utilize the load balancing feature? Pardon my ignorance of the obvious. I know this is really basic stuff. I still have so much to learn


Again thank you all for your help!

Cheers

Check your subnet setting. Sounds like there may be an error there.

 

[reynolwi]

Dual WAN ports do require seperate Internet connections. It can be 2 DSL or DSL and Cable or 2 Cable, but it does require 2 physical connections. There are several good routers out there. I use symantec at all my locations because of the IPSEC VPN thats built in. Technically you could go to best buy and get a router/firewall but depending on what you are doing it might not be recommended. Until i changed over to the symantec routers i was just using a regular d-link router you get from bestbuy.
