Network Assistant is a real-time communication utility for the office environment, including channels-based chat, shared whiteboard, message board and instant messaging. It is intended to be used in small office or home office (SOHO) local networks.
Network Assistant does not require an Internet connection or a dedicated server and supports IP Multicast technology that allows traffic-friendly group messages.
Network Assistant offers some surprising and cool features such as user details, file transfers, remote processes control, remote screenshots, activity tracking and more.
Network Assistant is simple, efficient and may be used instead of old good WinPopup (however, Network Assistant can work with WinPopup well too).
Network Assistant has multilingual interface. In addition to the base English, Network Assistant supports another languages.
