Agent running a SHELL command

Hi,

I had an agent that was working and got 'wacked' by the Notes Admin by 
mistake and it has since rolled off backup tapes.  This leaves me with 
the frustrating task of figuring out what I've already figured out.

Here is a potion of the code :
I_RetCond= Shell ("CHGOWN OBJ('\lotus\domino\dvlp\ffdvlp01
\ftp\Choicepoint\Attachment.txt') NEWOWN(newid) RVKOLDAUT(*YES) SYMLNK
(*NO)")

The directory structure is correct, QNOTES has access all the way down 
the structure.  The file exists as well.  Essentially, when an email 
arrives with an attachment Domino saves the attachment in the 
directory.  I need to run a SHELL command to change the owner.  

Every time the agent runs.  I get :
09/12/2006 15:26:43   AMgr: Agent ('Extract CP File' 
in 'mike/FFCP.nsf') message box: Error: File not found Error #: 53 
Line: 37  I_RetCond: 0            

Is there anything anyone sees that I'm using incorrectly.

Thanks, 

Mike.
