DHCP Not Working

I have a DHCP server on my network and my Windows 2000 station will not find it durring boot. Other stations on the network find it and get their IP Addresses but I must provide a static IP for the Win2K to connect to the network. When booting with DHCP it gets assigned a 196.x.x.x address and my network is 10.127.20.x.
 
is the card reporting any ip address when you use DHCP?
 
try reinstalling tcp/ip. That address indicates that there is a problem with tcp/ip. I have come across that several time here at work.
 
Tryed uninstalling, restart, reinstalling, restart TCP/IP and the results were the same. I then uninstalled all networking components and reinstalled them with the same effect. When trying to do DHCP, I check the ipconfig /all and it shows the same IP address (169.254.58.58) but it also show a line "auto configuration enabled". Perhaps that is a clue. I can put a static IP in and it connects fine.
 
The DHCP for the entire network is a SMC Barricade router that is serving all the DHCP to the rest of the network. It is at 10.127.20.1, though the server is a static IP address but the rest are dynamic.
 
I would recommend a little troubleshooting. Try connecting the machine your having a problem with to one of the ports a successfull machine is using. REboot and see what happens. Or you could always try going through a command prompt typing: ipconfig /renew and see if it renews with the correct ip. Make sure to have dhcp turned on in your win2k.

 
Have you checked with SMC for firmware upgrad, FAQ's etc. Make sure it is not a router problem. I noticed at the beginning you said my windows 2000 machine, sounding like you only have one.
 
My network configuration is:
1) NT4 Server (SP6a)
1) Windows 2000 Professional (SP2)
1) Windows 98 SE
1) Windows 95
1) SMC Barricade Router (Latest Firmware as of 2/14/02)
1) Red Hat Linux (Not Currently Running)
1) OS/2 Warp (Not Currently Running)
 
Swapped ports with working system and no change. I also made registry change as per MS to create IPAutoconfigurationEnabled value as 0 to supposedly disable the auto configuration which also didn't work.
 
If you manually assign an IP can you see around the network then? Perhaps you have a bad NIC. Marc Creviere
 
I'd bet it has something to do with the NIC. I had the same problem with a new machine here not pulling IP's. The address your getting is an automatic assigned if it can't find a dhcp server. With mine I switched the PCI slot and that fixed it. Matt Wray

I can manually assign an IP address and it works fine. I will try changing the slot as I have seen that work in other systems before for whatever reason.
