Permission Denied On ASP Page

last week I moved the folder of my Intranet application to another disk of the same server.

After this change all the ASP page return this error:


Microsoft VBScript runtime error '800a0046'

Permission denied: 'CreateObject'

/DocxTecnici/infotec.asp, line 22

For all the page, the row 22 is:

Set Fso = CreateObject("Scripting.FileSystemObject")

In the old location (C:) the application worked properly.
To move the application to disk D: I've followed this step:

1. Stop the IIS services
2. Move the Folder to disk D:
3. Change the path of Home Directory

The permission on the folder are the same of the old location

The version of IIS is 6.0
