Device manager shows yellow triangle beside this entry associated with
NIVIDA Networking Adapters. Windows cannot load driver for this
hardware.This appeared after SP1 installation failure. Tried system
restore three times it failed to restore on each occasion. Can this
entry be restored? No problems are apparent since noticing this.
Thanks

It's exactly the same problem that I had John and I honestly do not think
there is any remedy other than re-installation of Vista. I spent a few days
looking around various helpful sites without success and then contacted the
PC manufacturer. They advised me that restore would not work but told me to
try re-installing the network card drivers. I did that from my recovery CD
and also tried the drivers from the network card providers site but neither
set sorted the problem out. As far as I can gather, the WAN Miniport is a
virtual device and does not really exist. It is associated with the network
card though. The PC manufacturers said also that if the re-installation of
the network card drivers did not sort the problem out, a system recovery or
reinstallation would be necessary. Good luck, it's not so bad ad recovery
did sort the problem out.

John,

I had this same problem when I uninstalled the SP1 RC Refresh 2 service
pack. It's my understanding that it loads this driver onto a system for
forward looking compatibility . I did not have this entry in Device Manager
prior to it being installed on my system and even to this day it has nothing
to do with my system's hardware. It was loaded into my system under Network
Adapters during my install of SP1 RC Refresh 2. There must have been
something on my system at that time that possibly required it for future
use. I simply deleted it with no detrimental effects.
This entry was not loaded into my system after I did a clean install of
my Vista Ultimate x86 and installed SP1 RTM. I just checked again and it is
not there.
When I was researching the cause of this I happened upon the article
listed in the link below. I hope this helps you solve the problem.

I ran into something like this before.

I have information on my site of how I fixed it:

Basically, the “WAN Miniport (IP)” seemed to be messed up, and I couldn't
get it re-installed.

I have to remove the entry from the registry, then from Device Manager, then
re-install it using a program called "DevCon" (available from Microsoft,
http://support.microsoft.com/kb/311272).

Note: I only did this under XP, not Vista.
