The FileSystemObject only knows how to do copy  operations to the native
file system including CIFS file  systems (Common Internet File System or
Windows Network Sharing) because CIFS provides a mechanism for treating a
network location as a drive.

In your example, though, you're attempting to retrieve a file using the
HTTP protocol and the FSO simply doesn't know how to retrieve that kind of
file. That's why you're getting the 52 Error.

I'd suggest you either work  with a drive  mapped to the Intranet location
or go to http://msdn.microsoft.com and investigate the use of the XMLHTTP
object.
