Red Hat / Fedora :: Exporting Display Between Servers - Getting Error

I am using Cygwin and Xming server to bring back the display from Linux server to a Windows machine.

I am following the below steps :-
1.Close down all X Servers
2.Run XMing - XLaunch
3.Select Multiple windows
4.Select Start no clients
5.Tick No Access Control box
6.Click Finish
7.X Server starts and you should see icon in tray
8.Run Putty/SSH in Cygwin
9.SSH to server you want to connect to
10.Enter: export DISPLAY=192.168.0.1:0.0 (replace 192.168.0.1 with your IP)
11.Run dbca.

On using similar steps I can bring back the display from some Linux servers, but not from others, can you please let me know what the problem is and what things I need to verify. I am not getting any error, some of the last lines from the message in the log states :-

winProcEstablishConnection - winInitClipboard returned.
winMultiWindowXMsgProc - XOpenDisplay () returned and successfully opened the display.
winClipboardProc - Hello
DetectUnicodeSupport - Windows XP
winClipboardProc - DISPLAY=127.0.0.1:0.0
winInitMultiWindowWM - XOpenDisplay () returned and successfully opened the display.
winClipboardProc - XOpenDisplay () returned and successfully opened the display.

I did a grep X11 /etc/ssh/* the result is as following :-
/etc/ssh/ssh_config:ForwardX11 yes
grep: can't open /etc/ssh/ssh_host_dsa_key
grep: can't open /etc/ssh/ssh_host_rsa_key
/etc/ssh/sshd_config:# X11 tunneling options
/etc/ssh/sshd_config:X11Forwarding yes

/etc/ssh/sshd_config:X11UseLocalhost yes
