NT4 Stand Alone Servers DHCP

Hi

I've had a nt4 standalone server (lets call this one "AAA") running for a while now as a gateway (using comtun). AAA is mainly used as an internet sharing device for my home LAN. a hub is connected to the second nic on AAA and finaly, a few PCs are connected to the hub. This is working perfectly, all the pc are getting the network configuration through the DHCP on AAA.

Last night, I built a second nt4 stand alone server (that we'll call "BBB" (how original)). When connected to the hub, BBB's NIC doesn't receive the network configuration. At first I thought that the NIC was having a glitch but I connected the NIC directly to my cablemodem and I was able to surf the net. I tried putting manually an IP address but then again it didn't work (well maybe I did an error on that part, it was around midnight).

AAA's second NIC is 192.168.1.1 connected to the HUB. AAA is a DHCP server, DNS server and does SOCKS.

All help is appreciated!

first thought is the cable
cat5 568b specs?
what are you using to share the connection (NT doesn't have ICS)
enough leases in your dhcp scope?

What services do you have running on BBB? Many services like DNS and DHCP dont allow you to have a DHCP address, and require static IPs for the servers.

Yep, the cable is cat5 and is working if i'm conecting a laptp.

DHCP scope is from 192.168.1.50 to 192.168.1.250 and I have 5 pc connected.

Comtun, used to be called Comsocks from Linkbyte is doing the ICS. To what I know, it is doing a very good job.

try forcing the NIC to 10mbit half (as a test)

stevenlewis

also try the static ip (make sure it's unique, and correct) and see if you can ping

my two cents:

I would first try to connect BBB via a static IP (<50) as stevenlewis sugested. Eliminate network connectivity as the issue, then go from there. And you sound like you have a grasp on what you're doing there, but make sure subnet mask is 255.255.255.0 (or appropriate class C to match the others) and gateway is 192.168.1.1.

Also, what happens when you boot BBB and do ipconfig /all at the cmd prompt?

what service packs on the Nt's?

The NIC is working if i'm connecting it to my cablemodem (using the same cable).The hub is a 24 port all on autodetect.

I tried to set a static IP and still can't ping (when pinging i'm requesting 192.168.1.1 and get request time out)

Here is the result of a Ipconfig /all
C:\>ipconfig /all

Ohh I might have found something...

If i'm connecting BBB to AAA 2nd NIC with a cross over cable. It works. And on the HUB, it seems like BBB's NIC is doing 10mb, not a 100mb.

Soooooo could it be the hub that screws up ? Its a 24 port BayStack 252 10/100 HUB (It's only a hub, I don't have the "master" to configure it but usually, when no master is present, they are supposed to be on auto detect.

Any ideas ?

I changed the NIC and tadam!!

I just can't believe that for some reason, the hub can't stand slower connection. Sounds wierd but I appreciated all your help guys!

stevenlewis

Glad it working!

dohsky just FYI, if it's a managed hub, which it sounds like it is, often times the ports are configured for a specific speed, same way you can do with a NIC, and also most managed switches have the capability of converting particular ports to uplink, which basically swaps the contacts like a crossover cable. I know you got it worked out, but just wanted to add that two cents for future reference. You may have your ports staically set to 100 only etc...
