Hi, I'm having trouble getting airtunes to play to my remote speakers. It worked as of this morning, but I moved the box to the other side of the room and added a printer. Ended up reseting the airport express. It's set up with a green light, but when I attempt to play music I get "An error occurred while connecting to the remote speaker.... An unknown error occurred (-3256)" etc. I've upgraded the airport firmware, reset settings for AEBS and the express, restarted the computer, and now I am out of ideas. Also, I checked online and a ton of websites, including Apple, say to go into the firewall and stop blocking UDP (or something traffic). On Leopard, that option isn't there. In any case, that shouldn't be an issue... even turning off the whole firewall didn't help.
