Well, there are other IEEE 802.1X/WPA supplicants for WinXP, too.. ;-)

If the builtin supplicant is implemented correctly, it should work with
different EAPOL versions. The latest test version of the Microsoft
supplicant worked fine the last time I tested it. Which version of the
supplicant are you using?

Btw, WinXP has tracing option for EAPOL which does indeed log errors
into a file.. You will need to set EnableFileTracing to 1 in WinXP
registry My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tracing\EAPOL
and the log file will be written to %windir\tracing\eapol.log.

If nothing else works, you can change hostapd to send packets with
previous EAPOL version number by changing EAPOL_VERSION definition in
hostapd/ieee802_1x.h from 2 to 1.
