Newbie question: Help with installing tightvnc/ XORG on Redhat

[linuxnebwie]

Note: replace 'at' sign with at

Im trying to get a vnc server started and I would also like to setup a GNOME desktop environment.

I am using the following distro/release

[root-at-lab bin]# grep -H . /etc/*-release
/etc/redhat-release:Red Hat Enterprise Linux Server release 6.1 (Santiago)
/etc/system-release:Red Hat Enterprise Linux Server release 6.1 (Santiago)
[root-at-lab bin]#

[root-at-lab bin]# yum list | grep vnc

[root-at-lab bin]#

In installed tightvnc-server.x86_64

Now when I start VNC i get this error:
[root-at-lab bin]# vncserver

Warning: mtilab2.mtl.com:1 is taken because of /tmp/.X1-lock

Please set correct fontPath in the vncserver script.

I guess at this point, the log points to Xserver and I would like to reinstall Xorg
I tried to following a thread on this forum titled "How to install xorg on RedHatLinux?"
(I cannot post links to external webpages till I post 15 posts)
tatmtilab2 bin]# yum repolist
Loaded plugins: product-id, refresh-packagekit, subscription-manager
Updating Red Hat repositories.
repo id repo name status
epel Extra Packages for Enterprise Linux 6 - x86_64 8,347
rpmforge RHEL 6Server - RPMforge.net - dag

I then tried the next command- and that doesnt work

[root-at-lab ~]# yum install 'X Window System' 'GNOME Desktop Environment'
Loaded plugins: product-id, refresh-packagekit, subscription-manager

Setting up Install Process
No package X Window System available.
No package GNOME Desktop Environment available.
Error: Nothing to do
[root-at-lab ~]#

Here is the problem- I dont know where the server is physically located as the admin is out of town. How can I fix the Xserver problem and get my VNC/Desktop working. If you need output of any files, let me know and I will post it.

Im new to linux and loving it!!
