The Rogue DBA Mystery Cache

A ROGUE DBA IS SENDING INSULTS TO THE USERS. YOU MUST STOP THIS RENEGADE BY SOLVING THE PUZZLE BELOW.

The cache is NOT at the posted coordinates.  You must first solve the puzzle.

A rogue database administrator has rigged up some nasty SQL. This code will soon activate, and send an insulting message to users. Your job is to figure out the message so that you can warn the users.  

You have these clues:

• You have the message data, but it is encrypted using a famous visionary, tech titan's name as the encryption key. (This bearded titan will be at Oracle OpenWorld.)

   
  Here is the encrypted message:   DNRGQLZEBGCBWDJVCCLNPMACD
   
  The cache is at the location below-- derived from the last word of the secret message.
  

  N37 42.ABC  W121 53.DEF

  A = Number of letters in last word minus 6
  B = A
  C = First letter of last word plus 6
  D = First letter of last word
  E = Fourth letter of last word minus 5
  F = Second letter of last word minus 3
