CentOS - Apr 2007 - Having trouble with FreeNX, Need help to make it work perfectly

Hi thanks for the reply i am really grateful if you can tell me how to
make FreeNX work like charm.

I am really stuck with it, and after reinstalling the server is
definitely pissing off my boss.

Please help me thanks.

==========================
Please let me review how my FreeNX was screwed up.

After i fresh install my CentOS 5, I 'yum install freenx' and so if i
am not wrong
I actually install freenx 0.5.0-12 or something.... but i think ya shd be -12.

Ok... so after i install freenx through yum. I follow what's on
http://wiki.centos.org/FreeNX

I --adduser and --passwd etc. Then copy the
/etc/nxserver/client_id*.key over to my NX Client on Windows.

Initially all works out. The NX session starts and i can do what i
want over this remote session, and i proceed with updating of the
critical updates for other apps from yum.

The problem comes after i do this, right after the yum update.

I choose to reboot my server. I reboot the server over the NX remote
session. By going System -> Log Off -> Reboot.
The NX Client's Window automatically closed (in quite a violent way
with error msg). Then the server reboot.
After the reboot, I try to reconnect to Server again using NX. But
this time it fails with the following message.

I really do not know what's wrong. When i try to connect back locally
at my server. The GNOME UI is gone! I am now left with only the
console logon menu. This same problem happens everytime, even with
CentOS 4.4 recently.

(In the past, ard DEC 2006, I did the exact same thing on my CentOS
4.4 Server, it works without any problem EVEN with the same violent
exiting way, I have never have a problem connecting back to the
server. But recently after i failed my installation of CentOS 5 and go
back to CentOS 4.4, the problem starts to occur like what i have
mentioned. And I really did what was written on the wiki, nothing i
have done now is different from what i did in the past.)

Please, and sincerely please. Guys, if you all know what's wrong
please tell me, how should I solve it?
Did I miss out something? like installing of NX Node or NX Client on
the server etc?

Well explained or guide is really appreciated. Thanks, really Thank You.

First step, get X working on the local login first. If there is no running X 
server, FreeNX has nothing to connect to.

HTH, 
Tim

Hi

Let's assume i give up trying to get X working. The reason is that
even after i typed 'startx' nothing is working, a serious fatal error
message was shown.

How about from fresh installed CentOS 5?
How should i do it?
