Weird networking problem

I am an independent admin helping out a client of mine. They have a
network with only two computers, the router is outside the office (in
the basement). We have a switch inside the office. IP addresses are
manually assigned. Both computers have no firewall but the windows xp
firewall.

They share a folder that is hosted on one of the computers, and
everything has worked fine for a long time. Suddenly late last week,
the remote system could no longer access the host system's shared
files. Can't get to the workgroup even. The weirdest thing is that
neither computer can even ping the other, but the internet never
stopped working perfectly.

The two computers' ipconfig/all outputs are below:

Computers have been rebooted. Switch reset. Tried DHCP but IP
addresses could not be obtained. I'll see if I can access the network
room, it's a building-provided service so that could be tricky.

Any clue about where to start looking?

Thanks.
 
Re: Weird networking problem

Looks like they use 2 static IPs from their ISP. I can ping the DNS server
and the computer named Server Computer (.60)
And you're saying both computers can get to the interent? Even the .59
computer (Remote Computer)? Because the problem appears to be with that
computer. Can you ping your router from that PC? If so, what about your
primary DNS?

Re: Weird networking problem

youre not getting out the gateway.

try pinging the gateway from each computer, if you cannot its not home or
is now not on your subnet,
and needs to be powered down and up, or reconfigured. from the sound of it,
thats an ISP provided Router. call them. see if they can get to it remotely.

if not, and its the property of your client,
if you know what kind and model it is you can look up its default settings
which are public,
and set one of your pcs to that subnet,different last octet, and that
gateway to gain access to it,
if it had lost power and went back to its defaut settings. or else you have
to get to it physically.

Re: Weird networking problem

do you see traffic on the icon in the tray?

wouldnt hurt to do a repair on the connectoids in network
(right click -> repair)
it will flush the dsn cache and reinit the connection assuming it can be.

Re: Weird networking problem

I'm curious... did anyone screw around with the MAC address? Both PCs have
exactly the same MAC.

gw is pingable, router is up. 60 is up. 59 no answer.


in this order:

are you SURE the 59 Machine is actually connected to the switch??
move the cable to a different port on the switch. they DO go bad.

check the cable- any heavy marks kinks etc which make it suspect?

got a spare known good cable ?

wouldnt hurt to do a repair on the connectoid in network (59) machine
(right click -> repair)
it will flush the dsn cache and reinit the connection assuming it can be.


might be a setting in the router has erroneously excluded the 59 machine
from access.
check this.


and if that doesnt work
delete the connectoid on the 59 machine
and make a new one. that will set all the data structures in the registry
straight again.

right good catch

and maybe the router is mac filtered and rules out the second one.
clueless.

Ive made routers emulate the mac from the pc but never
made 2 pc's the same. I dont know what they did here.

Re: Weird networking problem


is there a firewall running on the 59 machine...?
{which may be blocking icmp echo request}
if so, that can be part of the problem.

Blocking ICMP on the .59 computer won't prevent that computer from pinging

odd that both NICS show the same MAC address.
