Unable to contact your DCHP server

After resetting my modem 100 times (from tech support) re-installing windows xp, buying a new NIC, i still get the same error message when i do a ipconfig /flushdns, ipconfig /release and then a ipconfig /renew : "An error occured while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out." I'm currently plugged into my laptop (which works fine, win7) but as soon as i plugin to my desktop (before doing a full factory reset on the modem) i get no internet activity. There is no router involved, just a modem(RCA, Model: DCM 425).  I've went through 20 different blogs and i cannot figure out what the problem is.

ipconfig /all result:

Host name : ...... juby-qvfgt3vlfm
Primary Dns Suffix ........ :
Node Type : unknown;
IP Routing Enabled : no
WINS Proxy Enabled : No


Connection-specific DNS Suffix :
Description : Sis 900 Based PCI Fast Ethernet Adapter
Physical Address : 00-01-80-6A-E2-F3
Dhcp Enabled : Yes
Autoconfiguration Enabled : yes
Auto configuation IP Adress : 169.254.247.88
Subnet Mask : 255.255.0.0
Default Gateway :

I was running XP SP3 before i reformatted. I am currently running SP1. I've disabled my motherboards NIC and plugged in the new one. Still get the same results as i was before i reformatted. Like i said, laptop works fine. When i first got the modem it was plugged into my desktop with a limited or no connectivity. As soon as i plugged it into my laptop, it was up in seconds. Any ideas?

Thank you,
Justin

Answer
Make sure your DHCP Client service is running...
Startup the Services window (Start -> Run -> "services.msc"), then look for a line labeled "DHCP Client".  Make sure that the Status column shows "Started" and the Startup Type column is "Automatic".  If not, double-click on that line and make it that way.

HTH,
