I am having similar problems but with a mDNS error. I am trying to to get to mt-daapd from iTunes on a Windows XP and Windows Vista box. Neither of them see the share. However, they see each other’s shares.
I am running wireless and have varified that multicast was enabled. I am running mt-daapd nightly 1586 on Ubuntu Feisty Fawn and trying to get to the share from a windows box running iTunes with the latest version 7.3.1. Here is the output from starting mt-daapd in the foreground:
