Every time I am opening Itunes with the Bonjour service activated (which I need as using besides Airport Express and Time Capsule for a Mac Pro), I am getting in the event viewer the "ERROR: read_msg errno 10054 (An existing connection was forcibly closed by the remote host.)". I did intensive research on the net, tried with the Bonjour service set to manual qas many are suggesting, but to no avail; the error message in the event viewer repeat at least 4 times every time I am opening Itunes. A full reinstallation of Itunes and other apple softwares also did not help. Any suggestion ?
I am having this same issue and would love to know the solution. Everything worked fine for a month or so. Now I am getting "492: ERROR: read msg errno 10054(an Existing connection was forcibly closed by the remote host)
