i am running Windows Home Server 2011 and iTunes can't seem to connect to the iTunes Store nor run Genius on my Library. What do I need to do?

I am running Windows Home Server 2011 and have installed iTunes on my dedicated server, attached to my router. I can't connect to the iTunes Store nor run Genius on the server ONLY (iTunes runs fine on by two other PCs and my Apple TV and I share the libary that resides on the server). I am running a very current version of iTunes 64 bit. I have run the connectivity test and it failed.

My guess is that there is some setting in the Server software that i need to change to let iTunes access urls or computers on the internet. Does anyone have any experience with this software combination?

Thank you
