Вот тестовый вариант:
<script language="JScript" runat="Server">
var log = new ActiveXObject("ACNLog.Logger")
log.LogFileName = "C:\RBondarenko\GCF\WebServer\GCF2003_Online_Application\LogFiles\DevelopmentLogs.GCFServicesLog.txt";
log.LogEvent("APP ", "* ", "--" );
</script>
Если запустить данный файл локально(изменив его в html), то все ОК. Если через http, то ошибка.

Вот исходный код:
<script language=VBScript runat=Server>
Option Explicit
on error resume next
