I have looked at my WHS and the only thing I can think of now is the firewall.
On my system in the firewall on tab Execptions are 2 entries for subsonic.
They are added with 'Add Program'
the first is C:\Program Files\Subsonic\subsonic-agent.exe
and the second is C:\Program Files\Subsonic\subsonic-service.exe
I can not remember if these are set by the setup, or by hand.
