Unable to use network after running wizard

I have WinXP Home. My computer has two embedded network
interface devices. I just use one, and its connected to a
Linksys router/firewall which then plugs into a cablemodem.

The other day I was having trouble configuring disk sharing
with another computer on my home network and made the
mistake of running the network configuration wizard. I
guess I made the wrong choices because when I rebooted I
couldn't connect to anything on the network.

After realizing I had no network access I looked at the
Network Connections panel. Apparently a bridge device was
created. I didn't want a bridge device so I deleted it.
Maybe that was a mistake. Nevertheless there appears to be
no configuration which will work for me now and I've done a
lot of research on this subject.

I've tried both network devices in DHCP and static address
mode. I've sniffed my network, and in DHCP mode my computer
never does DHCP inquiries, it just does arp-whohas for the
default IP address. With a static address I can ping my
router and also ping my nameserver IP addresses but never
get any DNS resolution. Apparently that's because my
computer never does DNS queries to the stated nameservers.

I've turned off ICF and ICS. I've run netsh and netdiag. As
I write this I am booted from an alternate C partition I
backed up a couple of months ago and obviously the hardware
and wiring is okay. I don't see anything different about
the port configurations.

So what do I tweak, or uninstall/reinstall, in order to get
my original connectivity back. What utility can I run that
would shed light on this?

System Restore.
