I found this somewhere in the net. Don't remember the author,
but it is someone well known in this group.

With this you can check the unique hardware ID of the Ethernet-card

from netbios import *

ncb = NCB()
ncb.Command = NCBENUM
la_enum = LANA_ENUM()
ncb.Buffer = la_enum
rc = Netbios(ncb)
if rc != 0: raise RuntimeError, "Unexpected result %d" %(rc,)
for i in range(la_enum.length):
    ncb.Command = NCBRESET
    ncb.Lana_num = ord(la_enum.lana[i])
    rc = Netbios(ncb)
    if rc != 0: raise RuntimeError, "Unexpected result %d" %(rc,)
    ncb.Command = NCBASTAT
    ncb.Lana_num = ord(la_enum.lana[i])
    ncb.Callname = "*               "
    adapter = ADAPTER_STATUS()
    ncb.Buffer = adapter
    for ch in adapter.adapter_address:
        adress+=( "%02x" % (ord(ch),))
print adresslist
