Well, you obviously can't configure it in the configuration file, since 
we're talking about how the configuration file is located!  You can send 
a DHCP option to give it the name of the configuration file, *however*, 
there is something wrong with your TFTP server.  Under normal 
circumstances, there is no need to timeout here - the TFTP server should 
send back an error reply, and so processing the various nonexistent 
filenames should take only a fraction of a second.
