The systeminfo command doesn't work in the home edition of XP.
In the run box type "msinfo32" select Components | Network | Adapter. Then find the item: last reset.


There may be a better way but all the tweaks I have found have been pro version only.

NOTE from Allan (Forum Admin) - Two wonderful free third party utilities that provide all the system information you will need are: Aida32 and Belarc Advisor.
