[CentOS] NX and CentOS 5.5?

I am pulling my hair out here folks......
 
I am running CentOS 5.5 in command line only.  Reason being I am standing up an IDS system on it.  
 
I have installed the NX client/node and server pkgs.  I have installed the NX client for windows on a Vista box.   When I attemtp to connect from the Vista to CentOS, I get this:
 
NX> 203 NXSSH running with pid: 22080
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: 192.168.1.70 on port: 22
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 204 Authentication failed.
 
Now I have been googling and re-googling. Plenty of people have had the same issue, but I have yet to find a solution that works for me.   Funny that most of the stuff I'm finding on google is 4-5 years old!  I'm sure I am probably missing something so simple I will puke!
 
I think I read that someone did an install and it worked right out of the box!!  Incredible!
 
I'd really like to see a CentOS - NX configuration guide but couldn't find one.
 
Can someone just tell me how this should be configured....what changes do I need to
make and to what config files?
 
ssh (putty and WinSCP) works just fine for me in case you need to know.
 
If you need any particular information, please let me know.
 
Thanks.
 
Ray
