So, I have my Laptop, my media server, and my HTPC(Raspberry Pi).
When I installed RaspBMC onto my raspberry pi I noticed that I could get files off of everything except my server. And when i ran arp into the consoles of both computers the Raspberry pi returned everything except the server, and the server returned everything except the raspberry pi. I don't understand how this is happening and what is causing it, and any help would be appreciated.
The Raspberry Pi is also running through a powerline set.
