>>thanks for pointing me in this direction. I am trying it out and am adjusting the code you provided to return all the physical MAC addresses. Do you know if they will always be returned in the same order (I am concatenating them into a string and would need them to always be in the same position in the string)?

What would be the benefit of that as the code is so easy in vfp?
