Yet Another Windows Internet Connection Sharing Problem

[rick.kovalcik]

I'm trying to help a friend with an ICS problem.

The setup is they have an older Windows XP home machine running ICS
with two newer Windows XP pro machines behind it.

All the machines can see the internet.

The two XP pro machines can browse (Windows Networking) to each other.


However, neither of the XP pro machines can see the interface machine,
nor can the interface machine see the two newer machines via Windows
Networking.

IIRC ping works in both directions.

Now it gets interesting. The ICS machine is 192.168.0.1. The sub
machines are 192.168.0.100 and 192.168.0.101 (as reported by ipconfig).

nbtstat -n shows what you would expect on the sub machines.

On the ICS machine it shows:

.....
LAN2
Node IpAddress: [10.10.0.1] Scope Id: []
GALTINEL <00> UNIQUE Registered
KEEPNET <00> GROUP Registered
GALTINEL <20> UNIQUE Registered
KEEPNET <1E> GROUP Registered
KEEPNET <1D> UNIQUE Registered
.. .__MSBROUSE__.<01> GROUP Registered

Where does the 10.10.0.1 come from? I'm wondering if that is the
problem?

Unforutnately I don't have an XP home machine to play around with so I
am stuck trying things on the friends machine.

Thanks.

Rick,

Let's start by looking at "ipconfig /all" for all computers please. Don't edit
anything.

I'm betting that you have a problem with SMBs. This will be most likely caused
by a NetBT setting, or by a personal firewall problem.

We'll work on nbtstat later.
