Setup fails to upgrade Exchange 2000 if Microsoft Windows Explorer has an open M: drive window.
This behavior can occur because open windows have handles open to the Installable File System (IFS); therefore, the IFS cannot upgrade.
To resolve this behavior, close any open windows to the M: drive.
This is by design.
