Re-install NT Networking?
I tried to update my NIC card from a 10meg ISA to a 100meg PCI (3com
3c509 to 3c905), but it has turned into a disaster.
First I tried removing the old NIC in control panel/network, shut down,
removed the old card, installed the new, and rebooted. Installing the
new driver worked, but then NT wanted to reboot again and afterward I
had no network connectivity, no services or protocols in control panel,
and could not add any because they are 'already installed'. ipconfig at
the command line reports 'Fatal error: inconsistent registry entries'.
I googled and found that changing NICs while VPN client software is
installed is a bad idea, so I shut down, restored my system partition
(which I had backed up before making any changes), put the old NIC back,
and rebooted. All was as before I started.
Then I uninstalled the Nortel VPN client, let the uninstall reboot the
system - and was left in exactly the same situation as before, i.e. no
connectivity, no services or protocols in control panel/network,
ipconfig fatal error.
I restored again, but this time left the new NIC in place and just
replaced the old driver with the new one, using the old file name. This
allows me to run on the new NIC (although Event Log can't understand
it's messages because NT hasn't read the .inf file), and the VPN also
works, but I still have no services, protocols, or bindings in Control
Panel, and if I close the Network applet by clicking OK, it 'reviews'
the non-existant bindings and trashes my connectivity all over again -
so I can't leave it like this.
Is there a way to *completely* *uninstall* networking so I can start
over clean? I really don't want to re-install NT just to change NIC cards!

I deleted every registry key that appeared to have anything to do with
networking, and got as far as a "Windows Networking is not installed,
would you like to install it now?" message from the Network control
However, installation fails with numerous "Registry subkey already
exists" messages - yet Regmon shows "not found" for all keys queried.
I reluctantly conceded defeat (for the moment) and installed XP SP2.
