Windows 7: Xbox only finds one PC on network

Hi, I have a desktop (Windows 7 Home Prof) & a laptop (Windows 7 Prof). Both are configured for media sharing and both find my Xbox 360 under network sharing, but my Xbox only finds my desktop - which is annoying as currently most of my media is on the laptop!



WMP 11 is not the most user friendly of programs and I'm in unsure territory - can anyone advise me if there is something I can do before I download Orb and have another program running in my task bar?

I have enabled media sharing on the libraries - after that I am pretty much lost/to scared to do something in case I mess things up....

Thanks ~Cess
