I currently have a homegroup setup and if my computer is asleep no one else in the homegroup can access the files that I've shared. Is there a way to automatically wake upon someone trying to access my files?

If your system has Wake On Lan (WOL) capabilities, you can enable it in the BIOS - this keeps the NIC "listening" for a specific packet, and if received, will wake up. However, you may have to do some additional configuration in Windows to get it working.
