Monitoring Network Bandwidth in Windows 98

In Microsoft Windows 98, monitoring network bandwidth utilization on peer-to-peer file and printer shares was achieved using the built-in System Monitor utility (sysmon.exe), frequently paired with Net Watcher (netwatch.exe). While Net Watcher tracked which remote users were currently connected to shared folders and printers, System Monitor provided real-time graphical tracking of throughput and bandwidth metrics. Together, these tools allowed administrators and users to measure exact data transmission rates across peer-to-peer connections.

System Monitor: Real-Time Bandwidth Utilization

System Monitor was the core tool for viewing throughput statistics in Windows 98. To track peer-to-peer bandwidth consumption, users relied on specific performance counters under the Microsoft Network Server category. When file and printer sharing was enabled, this component exposed several key real-time metrics:

  • Bytes/second: Displayed the current bandwidth consumption generated by inbound and outbound share access.
  • Total Bytes: Tracked cumulative network data transmitted by the file and print sharing service.
  • Server Threads: Measured the internal processing load created by remote requests to local shares.

Users could also monitor the Microsoft Network Client to see data rates generated when accessing shares hosted on other peer machines, as well as the Dial-Up Adapter or specific Network Interface Card (NIC) counters for total physical interface throughput.

Net Watcher: Connection and Share Management

While System Monitor tracked raw bandwidth in bytes per second, Net Watcher provided administrative context. It allowed users to:

  • View remote computers currently connected to local shares.
  • Identify which specific files were open over the network.
  • Track how long users had been connected to shared drives.
  • Disconnect users or close shared files to free up bandwidth and system resources.

Accessing the Utilities in Windows 98

Neither tool was always enabled by default, but both could be added via the Windows Setup tab in the Add/Remove Programs control panel under the System Tools category.

Once installed, they were accessed through the Start Menu:

  1. Click Start, navigate to Programs, then Accessories, and open System Tools.
  2. Select System Monitor to configure bandwidth graphs via Edit > Add Item > Microsoft Network Server.
  3. Select Net Watcher to view active inbound peer sessions and shared resource access.
