Service Name: SharedAccess
Executable Name: svchost.exe -k netsvcs
Log On As: LocalSystem
Description: Provides NAT (network address translation), addressing and name resolution services for all computers on your home or small-office network through a dial-up or broadband connection. When Internet Connection Sharing is enabled, your computer becomes an "Internet gateway" on the network, enabling other client computers to share one connection to the Internet, share files, and use the same printers.
If this service is stopped or disabled, features such as Internet connection sharing, name resolution, and addressing will not be available to clients on the network. Therefore clients on the home or small office network may not be able to access the Internet and their IP addresses will expire, resulting in some clients using APIPA (Automatic Private IP Addressing) for peer-to-peer networking connectivity.
