Itune 11 Cannot Load Firefly Server But Android Phone Can?

Hi I installed firefly server on my whs2011 and have trouble loading it on my client pc, the strange thing is my phone with a DAAP player can load and play the music. So I thought it might be firewall problem, I disable the client PC firewall and still can't play music. Firefly is set to use TCP and UDP 3689.

So I thought it's my client pc problem, I then try using my router (with itune function) to stream and it works! So now I am confused, is it my server or the client has problem?

I use firefly svn-1737

Thx in advnace
