Checking for dropped packets

Posted on 2008-11-03

We have a Windows 2003 SP2 application server that I'm concerned is dropping packets somewhere between the server NIC and the final destination these packets need to go to (which is a server on the Internet).

I guess I need to use Wireshark or something to monitor, but I have no idea what to monitor or check for!

Can someone help me out?

Would Perfmon also be of any use?

    You need to isolate a single protocol you want to monitor.

    Once you know the protocol that you need to check you can capture the communication and browse the packets to see if anything is missing.

    You can also used PATHPING to the destination server to see whether any packets dropped along the way. This is adding traceroute and ping function together.

    You can build a simple scenario. Say you have a machine A and your server has IP Now when you start ping or any other traffic, it could be ftp or http, you can filter traffic using wireshark. It will show you the traffic is sent properly. On server you can filter the traffic and check if it is recieved or not and if it is dropped then why.
