When writing ASP code in Windows 2003 server, you may encounter the following error message "Parent path not allowed". The codes involved are:
Server.MapPath(../)
<!--#include file="../"-->
wait. Perhaps for security reasons, Microsoft has blocked access to the parent path in scripts, but this may cause trouble for our programming, especially when the original ASP code is upgraded. Fortunately, this setting can be turned off. Specifically, in the IIS Manager below, right-click on your virtual path, Properties, Virtual Directory tab, click the Configuration button inside, and the "Options" tab. There is an "Enable parent path", just tick it and it's OK.
Happy programming.
