While I agree that maintaining a client host file is a PITA.... It's not that 
much effort in my experience... And worth it in the long run. Unless you have a 
very dynamic network with backup clients constantly being added / removed.... 

I feel it's more practical than naïve... I now have a weekend of failed backups 
due to failed DNS lookups... I have no control over the DNS server...  As long 
as the client is up and responding on the proper ports, Networker should simply 
back it up.... What does it matter if the reverse lookup fails, and how is that 
more significant than backing up your companies' data ???
