DHCP from Cable Modem on Windows 2000

[Rod Miller]

I have set up a Windows 2000 advanced server box at home to serve as a NAT router for my home computers connected via cable modem. My cable service provides me with 3 dhcp leases. I can easily pick up a lease from the cable modem with a Windows 98 box or a Linux box, but I cannot get Windows 2000 to pick up a lease. The only way that I have been able to get it to work is to set up the box with a static IP address. A associate of mine has basically the same setup at his house with a different cable modem service and he is having the same problem. If anyone has any ideas on how to get Windows 2000 or NT 4.o to pick up a dhcp lease from a cable modem, I would certainly appreciate it.

Thanks

Here is a brief synopsis of my setup:

-Triple-booted worktation (Win98SE Primary, Win2KAS Secondary, and Redhat 6.1 as last option)
-Cable modem service provided by MediaOne (Boston, MA)

You are absolutely right when you say that the Win98 and Linux clients can easily attain an IP address. I have found after analyzing several log files that Win2K is looking for the DNS servers first. If I set the DNS server entries static, the Win2K client will attain the DHCP lease with ease.

Let me know if this helps.

I have a NT 4.0 server @ my house with 2 98 and 1 NT workstation clients. In my server I have 2 netcards 1 with a set static IP (10.0.0.1) and 1 with DHCP leased IP. I have no problems with the DHCP server (cable modem) giving me a IP address. What I do have that I didnot see you mention is MS Proxy 2.0 so I dont need any more than 1 IP address from my ISP (time-warner roadrunner)

hope this helps

I had the same problem, just wouldn't take it...not sure how i did it, but when i reinstalled the OS it worked... most important thing to be sure of it that your identification is proper, might be something with the domain, or maybe even your computer name... i know on rogers in toronto i've got no domain name specified, but workgroup is @home
maybe that'll help you out.
