<div>
The error is clear, the means by which you connect is not.<br />
<br />
When setting up putty, xming you have to make sure you setup X11 forwarding to localhost:0,0 or what is represented by xming.<br />
<br />
The tunnel set for X11 does not reach xming...<br />
Localhost:12.0 on the Linux box is an ssh tunnel back to the workstation but the putty config localhost:X.y is not the correct identifier for Xming on the workstation.
