Hi,

Sorry to double post, but getting nowhere fast with other posts....wondering
if this problem is worse that we originally thought?

Our setup:

Desktop PC (Win XP)
Wireless Laptop (Win XP)
Belkin ADSL Router

The desktop is connected with a network cable to the router. The laptop
connects wirelessly.
Both can access the Internet.

We're trying to set up a workgroup so that we can share files between each
machine, and also allow the laptop to share the Desktop's printers.

We had it working ONCE but, since a re-boot, it's all gone AWOL again and we
just can't get it to work again.

Chasing up some other tech support, we were told to try "pinging" each
machine.

We are doing this by IP, and when we ping IP from the laptop, to the
desktop, it provides us with a response.
However, when we try this the other way around, we get "Request Timed Out".
Does this mean the fault is on the laptop or on the desktop?

We've double checked the IP addresses we're using, ran through the create
network wizard at least 20 times, renamed the workgroup, renamed the PC's,
double checked TCP/IP settings (both are set to obtain IP and DNS
automatically).

Any advice on what to try next would be greatly appreciated, thanks.

Regards
nath.

Nathon,

The ping command is pretty low level, and doesn't observe too many restrictions
like file sharing. There are 3 common possibilities.
# Physical component failure. A bad cable, router port, and / or network card.

Be systematic in your diagnosis procedure.

Laptop can ping desktop, but desktop cannot ping laptop. Can laptop ping
laptop? Start there.
 
Hi Chuck,

Thanks for the advice. I will have a good read through those articles.

Quick couple of questions though..."Laptop can ping desktop, but desktop
cannot ping laptop. Can laptop ping
laptop? Start there."

.....and if it can? Then what?
....and if it can't, what then?

Regards
Nath.

Nathon,

First, what happens when "cannot ping"?
# If "unknown host", then you have a name resolution problem.
# If "timed out", then you have a connectivity problem somewhere.

If computer A cannot ping computer B, the problem could be in either Computer A,
the network, or Computer B. If Computer B also cannot ping itself, then you
have to start with Computer B, and fix its own problem first, then retest.
