ASP run in IIS6 500 error solution _ Application Tips

The login page is accessible, but when the files on the lower directory are executed, the browser simply jumps out of the following error page:


There is no other valuable information than that, because this site is normal on my computer, I guess it should be a problem with the IIS configuration (I've heard that IIS has increased security, whether there are restrictions), but my code is very standard ASP code AH, no third-party plug-ins used. But in the IIS properties for a long look, the relevant options have been selected, there is no response, is still the above page. On the home page on the chaos point, suddenly jumped out of another screen, to the effect of saying "no access to the parent path permissions." Strange, why this error, which is the default on IIS 5.0, is it canceled on IIS 6.0? Reopen the IIS property entry, select "Home Directory", click on the "Configuration" button above, the pop-up window to select the "Options" tab, found that there is no hook, the following figure:


Quickly hook it up, refresh, OK, familiar with the picture came out again.
To ask why this error occurred in my code, there are files on almost every page that contain several parent directories, such as <!--#include file=. /conn/conn.asp "--> and so on, so that not normal access. Alas, the abominable IIS 6.0.
