lsass.exe want non-Export Version

I'm like to find somewhere that I can download lsass.exe for WinXP SP2 that is not the Export Version.
Each day a get a warning from ZoneAlarm when the LSA shell initiates. I've tried every suggestion from the ZA and other forums. I deleted the program entry in ZA. After rebooting I added the lsass.exe program entry with Trust level = Super; Access checked for both Trust & Internet; and Server checked for Trust & Server. But I still get the warning.
I don't want to uninstall/re-install ZA because I have so many custom settings and Expert Rules.
Please show me where to seek so that I shall find.
