MAC Address

[Peter]

We have to find out the physical address of a machine with
two NIC. And someone suggest that we should quote the
first physical address returned by IPCONFIG as it is the
primary address.

However, from IPCONFIG / ALL, we find that the MAC address
is as follow:
Physical Address - A (Disabled)
Physical Address - B (Enabled)

Can we say that our physical address is B ?

Thanks

Network interface cards have physical addresses, not servers.

You can say that your server has two NICs and you can say that the physical
address of NIC A is a and the physical address of NIC B is b.

Thank you for your advice.

Since NIC A is disabled, can we say that the primary
address is "b" ?

This is because the contractor asks us about the MAC
addressof the NIC and provide the primary address to him.

Thanks

Enable the NICs and try again. IPCONFIG won't display address for
disabled NICs. The MAC address is a string of twelve hex numbers such as
000304b67f9a sometimes shown colon seperated like this 00:03:04:b6:7f:9a

Dear Steve,

Thank you for your advice and I have a look again AND find
that it should be
Media State - Cable Disconnected

Thanks

Try the command

ipconfig /all

Even with the cable disconnected it should then show you the MAC address
listed as Physical Address.
