interesting experiment.

[Octavian Rasnita]

Most of Windows users don't have a network but only a single computer, or at
most 2.
If there is a network, there is a system administrator.
I am not a software engineer. I am licenced in Management, and I've worked
only in Sales and marketing.
But I want to be able to use an operating system that a lot of people say
that is the best.

The MAC address is required to diagnose certain network related problems
such as bad switches, faulty dhcp implementations from certain vendors,
network jabbers, broadcast storms, packet tracing and a host
of other uses.
Watching your network for arp trafic with tcpdump can tell you if your
windows box has come up onto the network and if the NIC is working.
Knowing which machine you are looking for on a multi-pc network means
knowing the mac address
especially if there is an ip address conflict.
Compound your problems by having a corrupted dhcp lease database under NT or
2 machines
set to the same ip 1 dhcp 1 not, and you'd like to know which
machine is where.
MAC addresses are unique, and many organizations use the MAC address to
track where
their computers (or the network cards in said computers) are.
Tracking a MAC address can tell you which segment on a switch a machine is
on, and
on complicated setups you can dump the MAC table to debug 802.1
bridging problems.
It is conceivable that on your home network you have personally
never neded to know the MAC address of your windows box,
and that is fare enough.
I have debugged network problems in seconds with knowledge, a few MAC
addresses
and a packet sniffer that have baffled others for weeks.
Maybe I am becoming disalusioned, but it seems so many people these days
have
no desire to know how things work, I mean really work.
If you understand how things work,
it is far easier to fix problems.
My underlying knowledge of ethernet makes solving most networking problems a
snap.
