Xming is a great way to launch X-windows applications on a Windows desktop. Once you've installed this (OSS) X-server, you can use PuTTY (SSH client) with the 'Enable X11 tunneling' option to start YaST2, the ZENworks Agent or any other X-windows application. Definitely a must have for Linux admins who occasionally work on a Windows desktop.
