Is there a way to trace TCP/IP traffic using NT?
A. As part of the Systems Management Server there is a Network Monitor module which enables the entire network to be monitored, also traffic over a modem. There is a limited version of this with NT 4.0 server, however only communications between the server and other computers can be monitored. The Network Monitor Service has to be installed (Control Panel – Network – Services – Add). There are also 3rd party products available that are superior to Network Monitor, such as NetXRay from http://www.cti-llc.com/cinco.htm which retails for around $999. Q. I do not have a network card, but would like to install TCP/IP. A. Microsoft provide a Loopback adapter that can be used for the testing of TCP/IP.
