GetAdaptersInfo() function instead. The IP_ADAPTER_INFO structure has an
Address member that is the MAC address.

Yes, I use that method also.
But if it is the question of getting the *unique* hardware
ID based on MAC, than I think that the string:
"444553540000"
... that sometimes can be returned should be skipped.
It has something with modems and dial-up (PPP).

GetAdaptersInfo() returns info on all types of network adapters, that
includes, loop-back, NIC, modems, dial-up's and VPN. If your looking for
the NIC then you need to examine the value of IP_ADAPTER_INFO.Type.

Hello,
Thanks for your answer.
I already write a program which use the function GetAdaptersInfo() and I
used it on many computers. But on one new computer type which use Windows XP
too, this
function give me a wrong MAC address . Then I look on microsoft site at the
following address :
msdn.microsoft.com/library/default.asp
and on the top of page there is:
Windows Server 2003 and Windows XP: Use the GetAdaptersAddresses function
instead of GetAdaptersInfo.
I am interested to try this function but unfortunatly I do not find some
declaration like PIP_ADAPTER_ADDRESSES and so on. Is anybody know where we
can find this kind of files descriptions ?
Thanks

What do you mean the wrong MAC address? GetAdapterInfo() works fine on all
our machines using XP (home, professional, SP1, SP2) and Win2003. What does
your code look like? As I mentioned before, GetAdapterInfo() can be used to
return information on many different adapters, you need to examine the Type
value of the IP_ADAPTER_INFO structure. Also, I have found that Windows
does not always preserve the order in which your adapters appear in the
list.

Replace:
printf("\tAdapter Addr: \t%ld\n", pAdapter->Address);
With:
printf("\tAdapter Addr: \t");
for (int i = 0; i < (int) pAdapter->AddressLength; i++)
printf("%02X ", (BYTE) pAdapter->Address[i]);
printf("\n");
The web site where i saw that adjustment is:
