Follow the Cygwin installation guide:
https://cygwin.com/cygwin-ug-net/setup-net.html#internet-setup
https://cygwin.com/setup-x86_64.exe
Install these packages:
Run these commands:
echo "export DISPLAY=:0.0" >> ~/.bashrc
mkdir -p ~/.ssh
nano ~/.ssh/config
now you are editing the config file for ssh. Add this text to the file:

and press control-X to exit and save the file. Then run:
chmod -R go-rwx ~/.ssh
to make sure only you have permissions in your ssh config folder.
First, to download a necessary file, you need to install and login to the Fermilab VPN. Go to:
Download the anyconnect VPN client and install it. Run anyconnect and connect to vpn.fnal.gov
Now you can go here and download the Windows krb5.conf: http://metrics.fnal.gov/authentication/krb5conf/
After the download finishes you can disconnect from the VPN (using an icon in the taskbar).
Finally, copy that file to (by default)1: C:cygwin64etc or inside a cygwin terminal: /etc
Now you can try to get a Kerberos token:
kinit <your fermilab username>@FNAL.GOV
kinit <your fermilab username>@FNAL.GOV
ssh dunegpvm03
once logged into dunegpvm03 (or another of the dunegpvms):
vncserver -list # make sure you don't already have a vncserver running
vncserver # start a new vncserver
vncserver -list # see the running vncserver
exit
take note of the \"X DISPLAY #\" shown with vncserver -list. Now ssh to dunegpvm03 again, but this time open up a tunnel to port 5900 + the display number, e.g. display number 3 use port 5903:
ssh -L 5903:localhost:5903 dunegpvm03
leave that terminal open, and open a new cygwin terminal (run cygwin again from the desktop shortcut or start menu).
In this window, run startxwin. That starts up the graphical Linux
window system on your computer. Leave it running.
Finally, open another cygwin terminal and run vncviewer. You want to
connect to localhost:5900 + your x display number so for the example
of 3 shown before you use: localhost:5903. You then put in your
fermilab password. Now you have a graphical desktop on a fermilab
computer.
Instead of the startxwin and vncviewer parts, you could have
installed the TigerVNC VNC viewer on Windows and connect with that.
The VNC server on the dunegpvm will keep running even if you loose your ssh connection. This can be useful to leave programs running for a while. It does take up resources on the server, so it is good to kill it when you are done. For x display number 3, you run:
vncserver -kill :3
on the dunegpvm to shutdown the VNC server.
