Active Server Pages error ''ASP 0131'' - Disallowed Parent Path The Include file cannot contain ''..'' to indicate the parent directory.

Apparently IIS configuration on a Windows 2003 server disallows the usage of ".." in ASP include files. You can easily solve it in this way

1. Go to your IIS Manager
2. Right click your web site
3. Choose Properties >
4. Select Home Directory Tab
5. Click ‘Configuration’ button
6. Select App Options Tab
7. Check the Enable Parent Paths
8. Click OK and your new configuration will be saved.
