Greetings,

I have a network of 5 computers + 1 windows 2000 server w/AD setup. 4 of the computers are win98 and one is windows 2000 pro. The windows 2000 pro will not get an IP address from the router wich is setup for DHCP, but win98 has no problem. Though troubleshooting I tried setting up DHCP on the 2000 server instead of the router doing the DHCP. and the win2000 pro machine got at address from the server. I come it will not get an IP from the router? and if I assigned any of the IP staticly the internet will not work. Why is this like this I have been banging my head on this all weekend. Or how can I set this up. Also I have a laser printer that need an IP assiged to it.
This is a bestdata Modem/Router 800R

Thanks for any help

When you have the pro machine connected to the router, have you ran an IPCONFIG /RELEASE, IPCONFIG /RENEW? Matt Wray

yes and it says cannot locate DHCP server

I'm thinking why the computer does not see that router, or why the router will not give an IP.

Have you checked to see how many clients the router is set up to support? Have you tried setting a static IP in the same range and see if you can ping the router? You might be able to statically assign and IP with all the same info, gateway, DNS, etc and browse... Matt Wray

DHCP is setup to do this use 192.168.x.10 = 192.168.x.100

So I have plenty of addresses

I think I might have soloved my problem okay listen to this.

Sense win2000 uses DNS for naming and stuff. Then should I use IP Forwarders to use my ISP DNS server, because my internal dns server does not have that info, and of course the win2000 machine will always look at the internal DNS server intill I use a forwader Right?

You got it about DNS, but that doesn't explain the pro machine not getting IPs from the router. Let me know if you figure it out...

ama299,

Can you open a command/dos prompt and enter
"ipconfig /all" [without the quotes]
copy the results and post back here.

Okay I got a little further on this problem. I got all the other computer + the server to get internet.

Still I the one win2000 pro machine that does not even see the router. I have tried a static IP and DHCP both I can not ping the gateway, but I can ping the all other machines, and all of the rest of the machines can ping the the router, and I can not ping the win2000 pro machine, but I can logon fine use the network shares.

It is a New 4400 dell P4 comp.
On Dells Forum there is a another person with this problem, but he has XP. I called dell and they said "I'm not going to help you fix your network" end of phone call. All of
these machines are plugged into the same hub. I have tried plugging into a different port on the hub.

Here is IP config /all shows This is just from memory

IP 192.168.1.5
Mask 255.255.255.0
Gateway 192.168.1.1
I have tried alot of different ways.
DNS ISP's DNS server and then internal DNS sever

Please Help this is driving me Crazy!

ama299,

First off, you need to do "ipconfig /all", copy the response and paste it in a post back here. There is more information in the reponse than you provided. Specifically, I want to see the Node Type and what the OS thinks the DHCP status is. Want also to see if there are other adapters and how they are set in the config.

Second, you have an IP of 192.168.1.5. I assume you set that because you were unable to get a DHCP adress. Let me confirm your DHCP range is 192.168.1.10 - 192.168.1.100. Switch back to DHCP on the adapter before doing the ipconfig above.

Third, I did not see a response to the question if you were able to ping the router. Were you able to?

No I can not ping the router. Okay I will post the ipconfig /all msg tonight when I can get to the machine.

Thanks

OK, then that's what we need to focus on. No matter how you configure the DHCP aspect, if you can't ping the router, it will never work. Things to check:
- Are you sure the adapter is installed/working correctly?
- Is there a link light at the NIC? At the router?
- Is the cable good? Is it straight-through, not cross-over?
- Are there any errors indicated in the Network control panels for Adapter and/or Protocol?

I have already verifed that:

The Nic card is installed. The card with ping all computers + access network shares with no problem, and logon correctly.

All Link lights are flashing

The cable is a standard CAT5 Straight-through
I will need to check to see if cable is good

There are no errors
I have tried two differnet NICs a 3com + Intel 10/100 cards both to the same thing

So I will need to try a different network cable

Thanks,

Sorry, I just reread your earlier message where you said you can NOT ping the gateway but you CAN ping the other workstations.

You mention they are all connected to a hub. Can you please describe the hub (make/model, number of ports, what's connected and where). I assume there is an uplink port to the router. Often hubs share the uplink with one of the regular ports. If so, when the uplink is in use, the shared port is unusable.

Just to confirm:
From the Win2K machine -
- You CAN ping other workstations
- You CAN NOT ping the router. What message do you get?
From other workstations -
- You CAN ping the Win2K machine
- You CAN ping the router

If you could also do an "ipconfig /all" from one of the working machines and include that, it would be helpful.

The hub is an Acer 8 port hub with one uplink I don't remember the model number right off hand, but I know I went to acer's website and could not find any info on it. I have tried two different ports on the hub Port 5 n 7.

From the Win2K machine -
- You CAN ping other workstations Yes
- You CAN NOT ping the router. timeout msg

From other workstations -
- You CAN ping the Win2K machine I will have to check on that tonight. It seems like I could not
- You CAN ping the router YES + internet works great

I can also get a copy of other WS ipconfig /all

Thanks for all your help

I did not get a chance to get the config, because everyone wanted to leave, but I did plug the computer in directly to the modem\router and worked great. so I think I will unplug everything except for the DSL connection, and the modem/router.

Thanks,

ama299,

Not sure I understand what you are saying here. If I understand correctly you plugged the Win2K server directly into the modem/router and it worked correctly. If that is the case, then

- Win2K machine is set up correctly for DHCP.
- Win2K machine, when plugged into multiple ports on the hub, did not work.
- Other machines, when plugged into the hub, work correctly.

My feeling, then, is the problem is the cable. Did you use the same cable to connect to the router as you did to connect to the hub? Try using the cable that worked connecting the Win2K server to the router and connect it to the hub.

Thats right except this problem is with just the w2k computer the win2000 server works fine.

I did not use the same cable and I did not use the router's DHCP i just assigned all the correct settings to the NIC in W2k computer and worked great. so somthing is happening between the w2k computer and the router. So tonight I'm going to plug in just the router and w2k computer into the hub and see what happens + I have new cables.

I hope it is just the cable

ama299,

Sorry, I got the Win2K computer and server mixed up. How did your efforts plugging the computer into the hub and the router with the new cables go?

It was the hub + wiring.

Sense I did have any info on this hub i did not know what there symbols meant by the port.

I had it plugged into the uplink port which all the win98 + server worked just fine. so I thought it was in the right port. NOPE

I guess it was suppose to be plugged into the shared port with a straight cable. Then all machines worked + there was a problem with the DELL nic so dell sent some jerk that replaced it. (lets just say he spoke his mind) worse sopport I have ever delt with.

Thanks for all your help
