Cannot see 2 PC's on home network

Asaf

Hi,
From time to time I encounter a problem with my home network (MSHOME1),
that my two PC's can't see each other in the view workgroup computers.
Both are running XP SP2, one is a Desktop and one is a Laptop.
They're both connected via hub to the internet, via cable-modem.
I also have a personal firewall, in which I've trusted their IP's.

When pinging each other, I can see them both.
However, when running net view, I receive the following error :

System error 53 has occurred.

The network path was not found.

Here is the ipconfig /all of the Desktop :

I stopped the Computer Browser on the Laptop, thinking that the problem
might be in the Browser - But that didn't help.

I will be most grateful if anyone can try helping me.

Thanks,

Asaf,

What type of Internet service do you have? How do you ping one from the other -
by name, or just by IP address?

Your problem - or first problem - is that the two are on different subnets. My
guess is 2 modems, and 2 cable broadband services?
STUDYROOM: 85.64.208.0/24.
OFRALAPTOP: 85.64.218.0/24.

This creates a segmented workgroup. With this setup, using NetBIOS Over TCP/IP,
you should expect browser problems.

<http://nitecruzr.blogspot.com/2005/08/browsing-across-subnets.html>

I have 2 alternative solutions for you:
1) Connect a NAT router to 1 cable modem, connect both computers to the router.
Cancel the other modem service. Elimination of 1 service for 2 months will pay
for the router.
2) Use IPX/SPX on both computers. Do this properly though.

My personal, and professional, choice would be #1. In a heartbeat.

Hi Chuck,

I took alternative 2 (Using IPX/SPX) as you've suggested - And it
worked !!

I couldn't choose your first recommended alternative, due to the fact
that both PC's are connected via hub on one modem.

I'd like to thank you very much for your help - The instructions in
your website were very clear and helpful.

Thanks again,

Asaf

Asaf,

Thanks for your feedback. I'm glad I was able to help, but sorry that IPX/SPX
was the best solution.

You sure you couldn't replace the hub with a router? You could still cancel the
second service. Why waste all that money paying the cable company?

Please don't forget - follow the instructions from Steve Winograd about removing
TCP/IP from file sharing. And use Layered Security.

Hi Chuck,

I did indeed follow Steve Winograd's instructions regarding the TCP/IP
file sharing - Thanks.

As for replacing the hub with a router - I might be a bit confused with
the options that I have.

Allow me to demonstrate how I've connected my 2 PC's to the internet :

Laptop ---- (Ethernet cable) ----- [Hub Port 3]

Desktop -- (Ethernet cable) ----- [Hub Port 2]

[Hub Port 1] --- (Ethernet cable) --- Cable Modem
---- Cable

My Cable company provides the internet infrastructure (So I guess I
can't loose them...) and the ISP company provided the Cable Modem.

If I switch the Hub with a Router, is there anything that I can gain
(Perhaps from a security perspective) ?
I know that I needed a Router if I had a wireless network at home. But,
as I'm connected via ethernet cables, then I thought that a Router
wasn't necessary.

I'll be happy if you can recommend doing something different.

Thanks again for you time and patience.

Asaf,

A NAT router costs the equivalent of 2 (maybe 3) months of cable Internet
service. Beyond that, the router is paid for, and you start saving money.

I've discussed the advantages and disadvantages of using IPX/SPX for file
sharing in my tutorial:
<http://nitecruzr.blogspot.com/2005/07/windows-networking-and-alternate.html>

Future supportability is another issue that you might consider. When you have a
problem, you'll have to explain that you're using IPX/SPX, and you'll probably
have to explain why. Some techs won't know how to support it.
