Monitor your network or dial-up connection. LinkLight will give you some new features and allow you to gain access to hidden Windows settings. It will give you the status on username, total bytes in/out, BPS in/out, IP address, Netmask, default gateway, DNS, MAC address, OS with build, and installed service pack.
Help desks and support departments can get relevant information on the remote PC (free to distribute/bundle with your software and Web services). By default, the program will alert a dial-up client if online, and a LAN/network client if offline.
