I have a few machines on my LAN. I can see the XP Pro machines from the XP
Home machine. I can no longer see XP Home machine from the other machines.
The disk on the XP Home machine has been used for backups so now I can't
back up.
I doubt a NIC can work half way but what are some known ways to trouble
shoot and perhaps resolve this problem?
The "ping" command is nice.
Open a Command window, and try "ping xxx.xxx.xxx.xxx" where you substitute
the IP address of the destination you want to reach, where the xxx's are.
Ping sends a packet from your machine, to the xxx.xxx.xxx.xxx machine.
That machine should automatically return the favor and send a packet
back. That helps prove that both transmit and receive work. The ping
command may even tell you the time it took, for the packet to come
back. (Of course, you need to know the IP address, or the symbolic address
of the machine, to use the ping command.)
This won't work with all machines on the Internet, because some of them
have ICMP turned off. But for your own home network, it is more
likely to work.
If you are connected to the Internet at the moment, you can try this
in a Command window. This shows I can reach a machine quite distant from
me, without losing any of the four test packets.
