It can be reliable on some machines, but I have already demonstrated on several computers that it is very unreliable. I ran that code on my PC over 20 times in a loop and inserted the entire return value strings in a table. No part of the string was ever duplicated in other records and not 1 had any semblance of my MAC Address.
