I have no tested 0.6.9 on Windows 2000 and don't know what to expect on
its functionality there. Your description seems to indicate that there
would indeed be problems that may end up with wpa_supplicant service
getting terminated unexpectedly.

When running wpasvc manually, you will need to add "app" as a command
line argument to get it actually run in operational mode. If you enable
debugging (set debug_level variable to 2 in registry
HKLM\Software\wpa_supplicant key), "wpasvc app" should show debugging

wpasvc will read the configuration from Windows registry. If you want to
try wpa_supplicant.exe, you can use the text file based configuration.
As a quick test, you could just create an empty configuration file and
run wpa_supplicant.exe with verbose debugging enabled (-dd on command
line). Check README-Windows.tx tfor other command line arguments needed
for this.

The default configuration in Windows registry (i.e., the configuration
used by wpasvc) uses ap_scan=2 by default, but yes, if you use
wpa_supplicant.exe, you will need to add ap_scan=2.
