I am seeing a strange problem in Zune desktop where I cannot sign in to the Zune service from inside the Zune software. I can sign in to zune.net just fine. I ran fiddler and it showed an attempt to connect to login.live.com:443 which returned a 504. I am running Win7 64-bit Professional, and am on a corporate network which has blocked Windows Live Messenger client connectivity. Just fyi.
