For Mac address, check
http://vbnet.mvps.org/index.html?code/network/netbiosenumlana.htm at Randy
Birch's VBNet. (Obligatory warning: Randy's site is aimed at VB programmers,
and since there are significant differences between the controls available
for forms in VB and in Access, not all of his examples port seamlessly to
Access. This sample is one such example: you can't add items to a list box
in Access the way his code is)

Not sure about Disk Id. Which Id are you looking for?
