Below is an example of how I deleted an object from a library from which I
am not supposed to have authority to.  We are concerned that a remote client
who is connected to our AS/400 might try to tamper with our system or start
snooping around simple by opening up an MS-DOS prompt on their PC.  Below is
an example of how I was able to delete an object using FTP from MS-DOS
prompt on my PC.

Is there a way to stop users from accessing the AS/400 using FTP from MS-DOS
prompt.

(MS-DOS Prompt)
C:\ftp 999.999.999.99
Connected to 999.999.999.99
220-QTCP at 999.999.999.99

signed on via FTP.
