Not sure if this helps but I was going step by step in the Getting Started
Experience Tutorial and when it got to the Database tab -- RDS Login part, I
was getting the Server could not be found or Coldfusion was not running. I
then went step by step through the tutorial again and I had not saved the
index.cfm file (it had changed the extension but was not saved yet). I then
rebooted and it works fine now.
