Dear Sgt Baxter, thanks for your insight re: port 453. I have the same issue as "Tyaris Major" - many, many PC's but nothing *at all* shows up. Don't know about the rest of you, but I have *NO* control over server settings, can Gordon add an option to allow me to control the port number it uses? Are there any work arounds to paranoid network security people who reject port 453?
