The Network panel shows the total number of connected users, and the rate at which packets are being sent from and received by the system:

Windows Networking Users — Shows the number of clients connected to this system.

This does not show users connected to other applications that may be running on this machine (for example, Microsoft Exchange or SQL server), only the users that have established a Microsoft Networking connection to the system.

Open Sessions — The current number of Windows Networking sessions open on this machine.

A session is defined as a user connection to a Windows Networking resource. For example, a connection to the ADMIN$ and C$ shares on a server by a single users is counted as two sessions.

Theoretical Bandwidth Limit — Shows the level of network traffic graphed against a "theoretical" maximum bandwidth for the network card specified. If there are multiple network cards, use Windows Network Card Display to select the one whose data you want to display.

Alarms can be raised in this panel for all network cards in the machine, not only the card displayed.

Note: Because of the methods involved in sending data, the actual maximum on an Ethernet network usually is approximately 50% of the theoretical bandwidth. The actual bandwidth can equal the theoretical bandwidth only when using full duplex Ethernet.

Token-passing network topologies (including TokenRing and FDDI) enable a theoretical maximum bandwidth much closer to the actual.

Selected Network Card — The name of the network interface card (NIC) selected for diagnosis. If there are multiple network cards, use Windows Network Card Display to select the one whose data you want to display.

NBT KB Received — Represents the rate at which NetBios TCP/IP data is being received by the system from Windows Networking clients.

NBT KB Sent — Represents the rate at which NetBios TCP/IP data is being sent from the system to Windows Networking clients.

Total KB Received — Represents the rate at which network data is received by the system from other network systems.

Total KB Sent — Represents the rate at which network data is being sent from the system to other network systems.
