LAN problems with DHCP

Hey,

I have a home LAN consisting of a router/firewall, which
connects to the Internet through DSL, and there are three
computers connected to it through a hub. There is DHCP
enabled, and most of the computers on the LAN receive
their IP addresses correctly from the server.

Up until yesterday everything was in order, when I managed
to install an additional network card into my desktop PC
running MS-Windows XP: now all that happens is that my PC
keeps trying to send packages towards the rest of the LAN,
but there is no response whatsoever (0 packets received).

1. I obviously removed the extra network card and
attempted to restore the previous situation. My (old)
network card is working correctly because pinging the
assigned IP address (Automatic Private Address assigned)
receives the packages all right.

2. There are no cable problems, either, because plugging
the exact same cable into the back of my laptop, I can use
the Internet just fine (this letter serves as living proof
to that).

It is painfully obvious that my desktop PC doesn't see the
rest of the network (hence the non-DHCP-assigned IP
address and actually seeing nothing in the View workgroup
window, etc.), but why? And, more importantly, how can I
work around this problem to get back my LAN?

Any and all advice is much appreciated.

Laters,

One possible solution is to run System Restore to go back in time to
before the problem started.
