Hi. I posted this problem a few weeks ago (8/10/2006), but left town before
I could resolve it. I thought I would start over again.

I have a network with several (up to 3) WinXP machines and one WinME machine
connected using a US Robotics wireless router. Regardless of which computers
are connected to the network, one of the WinXP machines, called Main, is not
visible in its workgroup, both when the workgroup is viewed from Main and
when it is viewed from one of the other machines. The computer can be
viewed, however, by typing \\Main in an address bar, and it can be pinged. I
want to know how to make it appear in the workgroup. Here are some things
I've already tried. There is some diagnostics output pasted below for Main
and one of the other WinXP machines that is working properly.

I have tried:
-disabling the firewalls
-looking at LSP/Winsock corruption
-setting NetBT to enabled
-removing IPV6

Here is various outputs for two of the WinXP machines:

Hi. I had originally thought that the nForce2 did not have a hardware
firewall, but apparently I was mistaken. I have not been able to find any
instructions on how to disable or uninstall the firewall for nForce2. I've
tried uninstalling drivers, but they seem to reinstall themselves exactly as
before as soon as I reboot. Anyone know how to do this?

Thanks,
Brahm

chuck

Hi Brahm,

From what I've learned here, and possibly depending upon what version of drivers
you have, the firewall is in the hardware. If it's a true hardware firewall,
and it's designed with modern philosophy, by default, all services like SMBs
(file sharing) are disabled. From Jack's experience, you have to run the
firewall manager to enable them.

http://nitecruzr.blogspot.com/2006/0...d-windows.html

If your version of the nVidia Access Manager (if you get that) doesn't work this
way, or if you don't have the NAM in your driver package, I think it's time for
you to contact nVidia Technical Support. If you do, will you PLEASE provide
the problem tracking number here, as I am going to start researching this issue
as a whole.

I don't seem to have the nVidia Access Manager installed and I also don't
seem to be able to install it. So I've put in a technical support request
with nVidia and I'll see where that goes. If they provide any useful
information, I'll be sure to post it here. I have a feeling they're going to
try to pass the buck to another company, though.

yachnin

According to nVidia customer support, the nForce2 motherboards do not have
the problematic firewall. Based on the diagnostics that I posted above, what
else could be the problem? I find that the fact the CPSSSERV diagnostic
can't find any active services for anything seems really strange, but I don't
know what it could mean.

Thanks,
Brahm
