NetSend

NetSend was a network messaging utility included with early versions of Microsoft Windows, specifically Windows 95, 98, and NT. It allowed users on the same local area network (LAN) to send short text messages to each other. The utility was accessed through a graphical user interface where users could type their message and select a recipient from a list of available computers on the network. Upon sending, the message would appear in a small pop-up window on the recipient's computer screen.

While functional for its time, NetSend was a very basic tool. It lacked any form of encryption, authentication, or message logging, making it unsuitable for sensitive communications. Its primary use was for quick, informal announcements or notifications within a small office environment. Security vulnerabilities were also a concern, as it was relatively easy to send unsolicited messages to other users.

Due to its limitations and security concerns, NetSend was deprecated by Microsoft and removed from later versions of Windows, starting with Windows XP. It was replaced by more advanced communication and collaboration tools. Today, NetSend is largely considered obsolete and is rarely encountered in modern networked environments. Its legacy is that of an early, rudimentary attempt at peer-to-peer messaging within a Windows network.
