The Network drilldown displays detailed information about the network activity to and from the system being diagnosed.

Recent network activity to and from this system
Network page
Shows the incoming and outgoing packet rates as an aggregate across all network cards in the system.
Shows the total number of packets (incoming and outgoing) broken down by network card.
Shows the level of traffic being received and sent by the system in kilobytes.
Shows the number of errors and retries on the network subsystem. A consistent number of retries or errors usually means one of the following:
- A network segment attached to the system is over-utilized.
- There are problems with a network card, cabling or other networking device on a network segment.
Recent TCP/IP activity to and from this system
TCPIP page
Shows different graphs representing the rate at which TCP segments are transmitted or received in the current Windows system.
When TCP transfers a stream data, it breaks up the stream into small segments
Shows the rates at which the fragmented packets are received and rebuilt.
When data packets are transmitted across a network via TCP/IP, they may be further fragmented en route, and need to be reassembled.
Shows different graphs representing the rate at which UDP datagrams are transmitted or received in the current Windows system.
UDP (User Datagram Protocol) is an alternative communications protocol to the Transmission Control Protocol (TCP).
Unlike TCP, UDP does not provide a sequencing service, so when UDP datagrams (packets) arrive at a destination, they are reassembled into a complete message via an end-point application that is active on the port(s) specified in the datagram.
Shows the rates at which IP packets are sent, received, and routed to other destinations.
IP datagrams (packets) are the message units that are transmitted across a network (and across the Internet) via the Internet Protocol.
You can view either the IP Datagrams chart or the IP Datagrams Errors chart. Select the desired option from the drop-down menu at the top of the chart.
Tip: To switch between IP Datagram and IP Datagram Errors view, click the arrow next to the chart name.
Which machines have NBT connections to this system
NBT page
Shows the machines that have a connection to the diagnosed system, and the corresponding level of traffic (in kilobytes) being generated between the connections.
Note: This is only for NBT (NetBios over TCP/IP) connections – that is, only Microsoft Networking connection over TCPIP.
Which users of other systems are connected to this system
Sessions page
Shows active connections made to the current Windows system by users on other systems.
Note: Remote Desktop sessions are not shown.
Shared resources on this system and any current connections to those resources
Shares page
Shows the resources on the monitored Windows system that can be shared with users on other systems
Shows the connections currently established to the shared resource selected in the Shares grid.
