Does it have to be localhost? I didn't install this machine, and just 
discovered the person who put Centos on only used "Storage" as the 
hostname (not fully qualified). I don't think it matters in this venue 
what the real hostname is as long as the Netbios name matches what you 
put in the host file.

So, now that I know things must be in hosts (I presume it needs to be 
that way on the AD as well?), do I need to do anything like Un"join" and 
then re"join" the member?

Any thing that clues us in helps, so I'm sure you've helped a bit.
