Preferred Solution: Monitor DHCP logs and traffic using Message Analyzer

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I want to capture both local and network traffic for connections and disconnections unrelated to http
Capture filter "(tcp.RST || tcp.SYN) && tcp.Port != 80 && tcp.Port != 443"

I found that I can do one or the other, but when I add both below, I capture neither ???

I've used Message Analyzer in the past to decrypt HTTPS traffic after importing the certificate used by the web server and it was a tremendous improvement over Netmon & NMDecrypt.    I'm looking at a trace I took of LDAPS traffic (TCP.port==636)
and the traffic after the SSL handshake Message Analyzer is not decrypting the traffic.   

Is the decryption sub-routines in Message Analyzer only supposed to work with HTTPS traffic, or should we be expecting to see success on LDAPS traffic as well?
Thank you,

My network seems to be slowing way down. I have basic networking knowledge and moderate Server knowledge. I, however, do not have very good analyzer skills.

Just like how we have an awsome sticky on RAID, I was wondering if we could have one on analyzing tools.

Personally I am looking for something either built into Server 2003, downloadable form Microsoft, or even free or expensive software that lets me monitor my network for traffic problems.

I am getting lots of users who are connected to a database on our server, and about every 5 minutes it looses the connection. I am trying to track the problem and don't know where to start.

Message Analyzer has not had any significant updates (apart from minor parser updates) for some time. The mechanism that out-of-the-box Message Analyzer uses to decrypt
TLS is based on access to the server certificate private key (and therefore does not work with ephemeral session keys). Since Message Analyzer is very flexible and configurable, I wanted to check whether it could be adapted to use SSLKEYLOGFILE information
and indeed the answer is yes.
The OPN programming language is Turing complete, but it would not be an ideal choice for implementing all of the necessary cryptographic routines that are needed for
this task ? it would be better to use existing cryptographic libraries. Fortunately OPN does include a mechanism for calling external routines ? the ?Handcoded? declaration:
binary DecryptData(string suite, byte ct, array<byte> ver, binary data, array<byte> key, array<byte> salt, ref array<byte>
iv, long ctr, out bool ok) with DeclarationInfo { Handcoded = true };
One simple way of using this is to place the ?Handcoded? definitions in a small OPN ?module?. The OPN has to be included as a resource in the DLL built from the ?Handcoded?
implementation. The resource is located by means of a .NET assembly level attribute:
[assembly: ExtensionOpnModel("TLSex.opn", false)]
The exposed hand-coded routine also needs to be decorated with attributes (for the containing ... Read more

Dear all,
it should be possible to
"Capture firewall discard Events - This feature allows you to discover how the firewall is affecting network traffic.  New messages tell you when traffic is blocked and associated IDs point to the specific firewall rule responsible
for dropping the message."
Does anybody of you know a little bit more about how Message Analyzer has to be configured to show which rule blocks (in my case Outbound) traffic?
This would be a great improvement to the pfirewall.log, where this important information is missing...
Best regards

My application does not have any network-like implementation except FlexNet Publisher for licensing. I expect it should connect only to license server.

When I use Microsoft Network Monitor then it shows only connections from/to my application and license server.

When I use Microsoft Message Analyzer then it shows enormous additional traffic for my application which I cannot explain. For example many events' source and destination do not match my local machine (BRWS/DNS/UDP modules), so it seems that my application
is kind of proxy (?) for them. Can anyone give some hints how to interpret Message Analyzer data, please?

I'm looking for a good network analyzer software that allows me to monitor the network. maybe have some features on discovering devices, ports, bandwidth in a certain amount of time, etc. Thanks.

A:network traffic analyzer

That would depend on the network topology. Any global network monitoring will have to be done with access to a common point where all the traffic converges. Addressed traffic between workstations will go directly between them via any switches and gateways in the path, so you can't do this with just a workstation.

Hi everyone!!!

I've been tasked with running message analyzer to determine if data is encrypted from an endpoint. We are using MBAM and want to ensure that any data sent to MBAM application server is encrypted. Now, we know it is via https, but, we still need to verify this

Is there a good network traffic/broadband monitor that actually keeps track of ALL (really ALL) traffic in a network?
I have used quite a few (eg, Ethereal, ntop, network probe) but all of them kinda keep track of only traffic that is coming in and out of the PC they are run from.

I need one that really tracks every single transaction that goes on in the network, including PCs talking to PCs, PCs talking to servers, servers talking to PCs, PCs talking to printers, etc.

Would help a great deal if they are FREE too!

Anyone know of any good ones?

Hi everyone!

Why is not possible in Message Analyzer to parse the ICMPv6 traffic inside the IP-HTTPS tunnel (at least up to my current knowledge) and only shows the ESP traffic when the scenario "Network Tunnel Traffic and Unencrypted IPSEC" is chosen.
I also tried to  capture on a specific interface, but the IP-HTTPS interface was not listed among the available interfaces.

For additional information, the environment of the DirectAccess i deployed on Hyper-V Windows server 2012 R2 which means that my DA clients are VM's on the Hyper-V.

I would be so appreciated if someone gives me a feedback on this :)

OK, this is my problem , I'm working in a complex environment with many networks and more servers (300+). Historically server hosted firewalls have been disabled and none of the internal subnets were bordered by firewalls ( thankfully they at least used
firewalls on the external interfaces ) . Documentation has also been poor. Not all the people who implemented some of our stuff still work here. The internal networks have effectively been completely flat.
The risks of this have finally been recognised and a project is in place to start implementing server hosted firewalls and on those internal subnets deemed important hardware based firewalls will also be implemented.
As you can probably guess however, from the initial statement nobody has much of a clue about which servers/applications are talking to what and how ( protocol or port) statefull/less. I'm looking for a tool which from a central location can monitor and
consolidate the network traffic between servers/applications and present the information in such a way that they could be analysed and present a baseline set of reports which would be a solid foundation for defining a set of firewall rules. Ideally the solution
would be agent less  (but that is not a deal breaker) . Is Message Analyzer the tool for this ? Or should I be looking elsewhere ? The OS landscape is overwhelmingly windows servers ( 2008 thru 2016 ) but there are a few RHEL servers ( although I don't

Support for decrypting TLS 1.3 connections in Wireshark has been present for some time and Message Analyzer, with some modification of its TLS OPN, can do it too.
The two ?handcoded?/external routines used by TLS.opn (DecryptData and ComputeKeys) both need extension. ComputeKeys needs to support the HMAC-based Extract-and-Expand
Key Derivation Function (HKDF) and DecryptData needs to support the new formats for the AEAD Nonce and AuthData.
Various type definitions need to be extended and some new types introduced (for handshakes like encrypted_extensions and extensions like supported_versions).
The biggest conceptual change that I made was to the routing of messages through the Message Analyzer stack. For TLS directly over TCP, the original Microsoft OPN files
dispatch the message from TCP to TLS then back to TCP and finally on to the end/application protocol (e.g. HTTP or HTTP2); one side effect of this is that some TLS handshake/alert messages are never visible in decrypted form ? one only sees the TLS handshake
messages sent in plain text and the decrypted application data. The new routing follows the path TCP -> TLS -> TLS again (if there are now some previous encrypted handshake/alert messages available in plaintext) -> TCP -> application protocol (e.g.
The new routing means that all handshakes (even encrypted handshakes), such as encrypted_extensions (and indeed the server certificate ? which is enc... Read more

I've captured a network trace on a 2008R2 server using the following commands:

netsh trace start capture=yes maxsize=1024

[reproduce issue for 20 minutes]

netsh trace stop

I've then copied the resulting ETL file (about 350MB) to a 2012R2 virtual machine (1 x vCPU 4GB RAM) running Message Analyser 1.4 (64-bit). I've opened the file in MA by double-clicking on the ETL file and applied an ?HTTP? filter to view only HTTP traffic.
 The server then goes to 100% CPU and sits there working through the data set at about one row per minute.  I give up and kill the process with the CPU time in task manager at about 2.5 hours and no data yet displayed.

I then open the same file on the same machine in Network Monitor 3.4, sort out the parsers and apply an ?HTTP' filter and after 30 seconds of 100% CPU get the data I'm looking for. It's not as pretty as Message Analyser but it does the job.

What am I doing wrong?  Right now it seems that while MA is no doubt great for some cool new stuff it cannot do the basics of Network Monitor or Wireshark.

Hi Team,
We followed to this url for use of remote interface capture
Remote Capture with Message Analyzer.

we followed the document of Message analyzer for capturing rdp session data.But that not helped us.
Both systems are in same network domain
source (physical , win 10 OS)
target  (vm , WIN 10 OS)

winRM services are running on both sides. 
Still we are unable to get the rdp data remotely.
Could u please suggest us to get the rdp session hex dump data remotely form message analyzer.

Hi there,
I installed for the first time "Message Analyzer" on Windows 10, and when I'm starting a local trace, "Loaded Modules" Errors are showing up. Here the lines from the log:

Message Analyzer seems to have no print/export as CSV/TSV. 
Log parser 2.2 doesn't seem to understand .matp formats. 2.2 seems to be the latest version.
logparser -i:netmon "SELECT * INTO test.csv from test.matp
says "not recognized as a valid NetMon capture file"

Are there other tools? I'm surprised this is not a common request. 

Message Analyzer can export as .cap files, but these particular traces either export badly or the traffic is something that wireshark doesn't handle. MessageAnalyzer shows it as fairly standard TCP traffic, albeit to/from IPV4-loopback, which is the correct

Hello everyone, 
I am new here, and trying to download message analyzer for the first time.  When I go to the link https://www.microsoft.com/en-us/download/details.aspx?id=44226
and click on the big red DOWNLOAD button, this pops up:
"Choose the download you want"
So then I try to choose, but I can't.  The file names aren't "active" and I cannot choose any of them.  
Anyone have any ideas?
Thank you very much for any help

Hi Folks
I worked with "Wireshark" and also with "Microsoft Network Monitor".
Both has Autoscroll you can choose or not.
I can't find this option on this new version "Microsoft Message Analyzer".
Could you help please?


A:Where is auto scroll in Microsft Message analyzer?

We don't have a real Autoscroll yet.  Though you could sort by time if you want to see the latest messages.  There are also known issues in how the scrolling works when loading a trace which we hope to address.

I couldn't get MA to Sync over our corporate proxy (which requires authentication). If you know how to get this working let me know.

A:Message Analyzer updates over an authenticated proxy

Yes, we did some more research and found there is a difference in how it tries to authenticate.  If your proxy requires authentication for a proxy request, then this exposes the issue.  We have a bug filed and we will look for a solution.
