Windows Server 2003 comes with Network Monitor, available as a Windows
Component in Add/Remove Programs, "Networking Tools". You can install it,
enable it on the appropriate network interface, and set it to sniff for
traffic matching a variety of filters. It's pretty powerful; the UI gets
the job done but won't win any awards for helping you figure out how things
work. You pretty much have to know what you are doing.
