Networking Services - services.msc

Hi,

I'd like to know which services are responsible for home
networking. i.e. which services do I need to be running
for others to have access to my shared docs?

I ask because I've tried the Profiles offered by
BlackViper, but noticed that when using his setup my
computer's Shared Docs is no longer accessible via the
Network Connections on both my CPU and the other CPU's on
my home network.

Thanks
