Windows Networking Problem caused by ICS?

[Bill Rankin]

I have an operating network with four XP Pro SP3 based computers, two wired
and two wireless on a Linksys router connected to a DSL modem. I added
another wired laptop (XP Pro SP3) that I have been using on a network at
another job. It used Novel Netware Client for Windows which I uninstalled.
I set it up for my local Windows network exactly the same as the others. It
uses NAV 2008 as does three of the other computers and one is using OneCare.
The Windows and OEM firewalls are off. All the computers are in the same
"Ournet" Workgroup.

From this added laptop, I can view and access the shared files on the other
four computers. I can ping the added laptop from the other computers and
ping the original computers from the added laptop. However, the added
laptop does not show up in My Network Places nor in "Entire
Network/Microsoft Windows Network/Ournet" on the other computers. Even
though I cannot see the added laptop, I can use Windows Explorer on the
other computers to map a network drive to the shared folder on the added
laptop!

I have checked settings many, many times, read Knowledgebase articles, and
looked in Forums and could find nothing that fixed my problem and made
Windows Networking display the added laptop. Any suggestions would be
helpful.

I did find something unusual that may contribute to the problem.

The added laptop is the only computer on the network that shows "Internet
Connection" (Sharing) as a Network Connection. I have tried to disable or
delete this network connection without any success. I could find nothing
that worked in the Microsoft Knowledge base. I have disabled the adapter
and the "Local Area Connection" and "Internet Connection" go away until I
re-enable the adapter. I set both connections so I could see when they were
active in the system tray. "Internet Connection" starts up right after the
"Local Area Connection" starts but runs at 8Mh rather than the 100Mh of the
Local Area Connection. I have recreated the network with the Network Setup
Wizard making sure I indicate that this and all network computers are
connected to a router not to another computer. But ICS is still there.

I have no idea if ICS is causing my network display problem but I would like
to fix both. Any help would be greatly appreciated.

Ensure netbios is enabled in the tcp/ip advanced properties (wins tab)

The "Internet Connection" doesn't indicate that Internet Connection
Sharing is enabled, and it has nothing to do with your network display
problem.

That connection represents your broadband router. It appears because
your router's UPnP (Universal Plug and Play) capability is enabled.
Clicking that connection lets you monitor and control the router's
operation. The 8Mb speed that it shows is the rated speed of the
connection between your router and your broadband modem.

To control whether the "Internet Connection" appears on Windows XP, go
to Control Panel > Add or Remove Programs > Add/Remove Windows
Components > Networking Services, and enable or disable "Internet
Gateway Device Discovery and Control Client".

It is. Any other suggestions. This has got to be something obvious.
Perhaps associated with the previous Netware installation. I checked and it
all seems to be uninstalled.

 

[Bill Rankin]

Yes, I have UPnP enabled on the router. And all the computers have
"Internet Gateway Device Discovery and Control Client" installed. Yet this
was the only system that had a "Internet Connection" shown as a network
connection in "Network Connections." Also when I checked its Properties, it
displayed that the connection was for Internet sharing of attached
computers. That does not seem consistent with your comments. Why would the
connection only be 8Mh for a computer directly connected to the router when
the LAN connection is 100Mh?

What if I disable UPnP on the router? Does that disrupt any normal PnP
router detection functions when I connect a new computer?

Steve,

I forgot to say in my earlier email that you are right twice. The "Internet
Connections" network connection disappears when I uninstall "Internet
Gateway Device Discovery and Control Client". Also, I still have the
problem of not "seeing" (but accessing) the laptop shared folders.

I still have those earlier questions to help understand why this Computer
was different from the rest. That may be key as to why I cannot see the
shared folders.

I am going to turn off UPnP on the router and see if there is any impact. I
do not believe I need its Linksys stated function to allow on-the-fly router
configuration changes.

Thank you for your advice,
Bill-R

Yes, the properties of the Internet Connection say "This connection
allows you to connect to the Internet through a shared connection on
another computer". That's inaccurate and misleading. It should say
"a broadband router or another computer".

The 8Mb speed is the rated speed of the connection between your
broadband modem and your router. It has nothing to do with your
computer's LAN connection.

It's fine to disable UPnP on the router. It won't have any effect on
connecting a new computer.

You're welcome, Bill. I don't know why the "Internet Connection"
representing the router appears on some computers and not on other
ones. I suspect that it has something to do with the driver program
for a computer's network adapter. I have two wireless network
adapters for my laptop computer. When I use the first one, the
Internet Gateway appears. When I use the second one, the Internet
Gateway doesn't appear.

Your router's UPnP function can help in automatically configuring its
firewall for applications like instant messaging. It isn't needed for
everyday use.
