NIC works with static IP but won't take DHCP

I have an older Dell Inspiron laptop that will communicate when the NIC is given a static IP but absolutely won't take DHCP.  It has a clean install of XP SP3 and fresh drivers downloaded from Dell.  The network card is a 3Com 3C920.  Does anyone have any idea why it won't take a DHCP address?  Thank you all.

Perhaps the router has DHCP disabled?

Hello, just a thought - Do you have a second NIC to try?
It may be the hardware is close-to-kaput. NIC's are inexpensive enough that it may just be better to first ensure a different one will work, and if it does, purchase a new card and save the headache of troubleshooting the Dell.
Good luck!

Is your DHCP client service enabled?

Yes, DHCP is very much enabled and kicking out to the other computers and laptops without so much as an issue.  I have had a PCMCIA NIC in this laptop and that worked fine.  I was hoping that someone might have heard of this problem before, perhaps a driver issue somewhere along the line (even though I put new ones on) or some weird little intricacy with this particular card.  This is unlikely to be something obvious!

More than likely its a problem in the TCP/IP stack in windows. Have you had any spyware issues lately?
Here is a guide to determine if this is the problem

I dont know - if another PCMCIA nic worked fine - then I am guessing a problem with the Dell driver, or the hardware is just not working correctly (could only speculate). You could dig further into the network settings, or even search out a different (even older) version of the driver for the specific card > or save time and install a new one. :-)
Good luck!

You could try, delete  the card from the system and reinstal it.

In the end I installed a wireless PCMCIA card which took DHCP no problem.  This somehow triggered the installed wired connection to work.  Don't know how or why!  I then uninstalled the PCMCIA card and the onboard wired card has continued to work ever since.
