[SOLVED] SBS 2003 + NETGEAR SmartSwitch + DHCP = ???

[tazinlwfl]

Hi!
Back again!
Purchased Windows SBS 2003 (R2) for my office and am in the process of setting up. I have a few questions about networking (why im here):

This is our current set-up, and hopfully I can just hook up our Server to it.
(I made it tiny)

We've used it for years as a P2P, but I'm trying to up the integrity/scalability a tad...

SO
I'm installing the server OS and it asks me about DHCP (it detected one already - I assume the Switch or the Modem)

I DONT want everyone passing through the Server to get online (everyone goes online, and I dont think the server could effectively handel the traffic)
I am hoping to just set up the server like it is on my handy diagram

I've read that SBS MUST take control of the DHCP, so I have to disable it on my Modem and Switch... is that right?

what would be your suggestion?

Yep, connect the server with a fixed IP address, and disable it's DHCP server. The router will provide DHCP services, and the server does not need to do so.

[tazinlwfl]

Wow Johnwill, you're fast!

OK, so when it prompts me "Windows detected a DHCP..." click "no" to use the Switch's?

and the fixed IP just has to fall within the range defined my the switch?

and another thing...
if you notice on the diagram we have two MACs running Leapard (OS 10.5)...
now, every book and site that I saw says NOT to use "example.local" as the domain if you want to use a MAC running OS X

but I noticed in the new version (10.5.3) it mentions a fix:

"Eliminates a delay when logging in as an Active Directory user in a .local domain"
http://support.apple.com/kb/HT1141

I know that they can log into the server and do "everything" everone else can, but has the "problem" with using a ".local" domain been resolved?

[johnwill]

I know nothing about the Mac, so I'll toss that question out to the field.

I'm not sure of the exact prompts that SBS presents during the installation, I've only seen them once. You want a fixed IP address outside the range of the router's DHCP server, but in the same subnet, and the DHCP server on SBS disabled.

THANKS!
I accidentially clicked "yes", so I will have to find out how to disable it later
and
I used the default NIC IP address, which had a xxx.xxx.1.xx and not a xxx.xxx.0.xx, so I assume that that will keep it out of the range of the DHCP if I make it something like xxx.xxx.0.0-20???

I know little to none about IP configuration (or DHCP)

[tazinlwfl]

Okay, I need some more help... But this is also approaching specifics about SBS

Like I said, I know very little about DHCP or IP Configuration...
My Modem is acting as the DHCP Server, giving me 192.168.1.x (1-253)
Thats all fine and dandy, but you mentioned putting the Server OUTSITE of that range?

What information will I need from the modem to migrate the responsibilities to the SBS?
It mentiones DNS, DNS Domain name, WINS (and node type)...

obviously I need some help

[johnwill]

Well, you need to configure the modem's DHCP server so it has a limited range, and not the entire class C subnet. Something like 192.168.1.2 through 192.168.1.99 should be more than sufficient for a small network.

Next, you assign a static IP address to the server in the 192.168.1.100 through 192.168.1.254 range.

[tazinlwfl]

I did something similar, i guess: range is 192.168.1.1-100, Modem is at 192.168.1.254 and SBS is at 195.168.1.101

When I set up the Static IP for the SBS, the subnet mask is 255.255.255.0, but what about the Default Gateway? Does that come from the Modem? what is "metric" (modem says it has a Metric value of 3)

and

I will need to input the DNS server address... the Modem lists a primary and a secondary, so I assume I use those?

When I try to connect the SBS to the DHCP (to establish a "scope") it cannot connect. I've tried a "real" IP and the modem's 192.168.1.254 IP

[tazinlwfl]

Okay Johnwill, I seem to have got it to work. It seems like it worked perfectly like you mentioned, with a little tweaking (had to make sure UPnP was enabled on my modem, which it wasnt, turns out)

SBS then notified me that a modem/router was discovered to have UPnP enabled.

I turned off DHCP on the Modem
I enabled DHCP on the SBS
the SBS now leases all IP addresses to the office... which is fine
(and the internet STILL doesnt pass through the server)

Appreaciate it
(i marked it as "solved")
