The login page can be accessed, but when the files in the lower directory are executed, the browser will directly jump out of the following error page:
There is no other valuable information except some, because this website is normal to execute on my computer. I guess it should be a problem with IIS configuration (I have heard that the security of IIS has been improved, is there any restrictions?), but my code is very standard ASP code, and I have never used any third-party plug-ins. But after checking in the properties of IIS for a long time, I have selected all the relevant options, but no response is true, and it is still the above page. While I was randomly clicking on the homepage, another screen suddenly popped up, which means "no permission to access the parent path". Strange, why is this error? This is the default on IIS 5.0. Has it been cancelled on IIS 6.0? Reopen the IIS property item, select "Home Directory", click the "Configuration" button above, select the "Options" tab on the pop-up window, and found that it was indeed not ticked, as shown in the figure below:
Quickly click it, refresh, OK, the familiar picture comes out again.
To ask why my code is this error, it turns out that almost every page contains files containing several superior directories, such as <!--#include file="../conn/conn.asp"-->, etc., so it cannot be accessed normally. Alas, damn IIS 6.0.
