Hi all,

An older Dell workstation had it's on-board NIC die on me. I am hoping the
rest of the MOBO is not also damaged, but the machine runs good otherwise.

I uninstalled all the Network Adapter devices in device manager, disables
the onboard Adapter in the bios, put a new D-Link NIC in place and rebooted.
The new NIC received an IP address and the proper gateway IP via DHCP
immediately. However I cannot ping the DHCP server (which is set to allow
ping) or see other machines in the LAN network.

I run dignostics and it says it can't ping the Gateway or the WINS server.
All the other machines can.

I'm puzzled. Is there some configuration that I might be missing?

Does AD in a domain register computers to the domain by MAC address?

However, I have a trusted Workgroup set up and those machines also don't
have a problem. Even when I designate the Dell as being in the Workgroup it
still doesn't see other machines.

Any ideas?

Thanks to all...

Hi all,

Here is a follow-up on the problem.
For some reason, last weekend, the PC in question began operating properly
with the new NIC card that I added.
Even though IE8 hade been installed a few weeks before, when I first opened
IE on Monday it prompted me to run through the Options setup for IE as if it
had just been installed and run for the first time. It is at that time that
I noticed the PC was now using the new Gateway to the Internet as well as
being accessible from other computers in the LAN and the local Domain.

It still remains a mystery as to why this problem appeared to magically
resolve itself over a weekend.

Oh well...

Thanks to all who took the time to read this post.

Most likely you have a 'smart' hub/switch which was slow to recognise that
the MAC address relating to the that IP had changed.

This is a common problem, and the only solution I know of is to power-cycle
the hub.
