What Was NetWatcher in Windows 95?

The NetWatcher utility (netwatch.exe) in Windows 95 was a built-in network administration tool designed to monitor and manage shared network resources, active connections, and open files. Introduced during the era when peer-to-peer networking became accessible for small offices and home networks, NetWatcher provided administrators and local users with real-time visibility into who was accessing their machine and what files were being used over the local area network (LAN).

Primary Functions of NetWatcher

NetWatcher worked in tandem with the "File and Printer Sharing for Microsoft Networks" service. Its core purpose was to give users control over peer-to-peer sharing. The utility focused on three primary monitoring views:

  • Connections View: Displayed a list of all remote users and computers currently connected to the local system, along with the duration of their sessions and the specific shares they were accessing.
  • Shared Folders View: Showed all folders, drives, and printers currently shared across the network, indicating how many users were actively connected to each share.
  • Open Files View: Listed individual files that were currently opened remotely, along with the names of the users accessing them and the lock status of the files.

Administrative Capabilities

Beyond passive monitoring, NetWatcher provided direct administrative controls to maintain system security and data integrity:

  • Disconnecting Users: Administrators could forcibly drop an active user’s connection if unauthorized access was suspected or if a machine needed to shut down cleanly.
  • Closing Files: If a remote user left a shared file open or a network crash locked a file, NetWatcher allowed administrators to close the file handle remotely so other processes could access it.
  • Creating and Managing Shares: Users could create new shared resources, set access permissions (such as Read-Only or Full Access, secured by share-level passwords), or stop sharing existing resources directly from the application interface.
  • Remote Administration: If the target computer had Remote Administration enabled in the Windows 95 Control Panel, a network administrator could launch NetWatcher and connect to another Windows 95 PC on the network to manage its shares and track connections remotely.

NetWatcher was an essential administrative tool for 1990s peer-to-peer networking, offering an easy-to-use graphical interface for network management before the advent of the Microsoft Management Console (MMC) introduced in Windows NT and 2000.
