TCP/IP Addresses

If the TCP/IP addresses were automatically assigned (using DHCP for example), you can check the logs/settings in the DHCP server software.

If all or some of the addresses were manually assigned (servers, printers, etc), it's probably the easist to use a protocol analyzer or a monitoring tool like the Fluke Lanalyzer to monitor and log all TCP/IP addresses. Of course you will need to move the monitoring software/equipment to all your segments so that you can get an accurate reading.

You could also use a tool like Microsoft Visio 2000 Enterprise. It contains a tool that will go out and query all nodes on your network. You can choose certain subnets or make it search the whole IP address range (not recommended due to taking a long time).

Another option would be to use the network scanner/port scanner of your choice (I like NMAP under Linux) and have it do a "ping sweep" It will give you a report of all responding systems. This would only be acurate if all devices were turned on.
The real solution to the problem is to get a network management application installed and configured. HP Open View comes to mind if you have the cash....

Hope it helps,

Use the netstat utility to query your domain. I can't remember the switches but if you use /? it will give you the info required.
It will only detail, however, machines that are currently announcing themselves on your domain.
Hope this helps!!
