Network Monitor 3.2 is a protocol analyzer. It allows
you to capture network traffic, view and analyze
it.
One of the nice features of the Network Monitor, is
that the packets are group per process.

Network Monitor 3.2 is available on Microsoft.com. The

New features in version 3.2:
-
Process Tracking: Now you can identify rogue
applications sending network data! View all the
processes on your machine generating network traffic
(process name and PID). Use the conversation tree to
view frames associated with each process.
-
Capture engine re-architecture to improve capture rate
in high-speed networks. Network Monitor 3.2 drops
significantly fewer frames that Network Monitor 3.1.
-
Find conversations: You asked for this. Many of our
users found conversation tracking to be difficult to
use as the view grew hard to manage, and it was
difficult to correlate the frames they were seeing
with the conversation nodes in the tree. Now, you can
quickly isolate frames in the same network
conversation. Just right-click on a frame and select
a conversation to track, and you will see all the
frames in that conversation. View TCP streams, HTTP
flows etc.
-
Extensive parser set: Parsers for over 300
protocols! As before, the parsers are fully
customizable.
-
Better parser management: By default only a subset of
parsers are loaded. You can load the full parser set
by going to Tools>Options>Parser and choose Full
vs. Stub implementations.
-
CodePlex Ready: In the upcoming months, we plan to
place all our Windows parsers on the Microsoft
open-source CodePlex site and allow the community to
modify and contribute parsers. You can find out more
information on this here. This version of Network
Monitor seamlessly integrates new parser packages.
-
Network Monitor API: Create your own applications that
capture, parse and analyze network traffic!
-
More extensive documentation of the API and NPL.
Access the documentation from Help > NPL and API
Documentation.
- PCAP capture file support.
-
ContainsBin Plug-in: Search frames for arbitrary byte
sequences or strings.
