Bernie, Your X display (your PC) doesn't normally accept incoming X11 sessions from others than the local host. There are two ways to get a remote system to create a X11 window on your screen: 1) run "xhost +*remote_hostname*". Note the + infront of the remote hostname. 2) use ssh to create a tunnel over your session to the remote host, that forwards port 6010+ back to your local X11 port.
When you use option 1), anyone on the remote server can open an X11 window on your PC. When you use option 2), ssh uses xauth on your userid at the remote system to register the credentials to use the tunnel. It will also set the DISPLAY variable to the correct port. This makes it easier to use, as the DISPLAY will always point to your PC, no matter what IP address you got today. And, very important, some other user who uses the remote system will not be able to create windows on your screen. My advise would be to use option 2. If you use "ssh", then use the option "-X" (upper case X). If you use PuTTY, then look at "Connection -> SSH -> X11" and select "Enable X11 forwarding".
