Hello Jason:
I think that you need the NetWorkView 3.1
You can download it from www.downloads.com
Just check some of the features (for $79.00 the license)
**********************************************
NetworkView is a compact and powerful discovery and network management tool for Windows NT4, 2000, XP and 2003.
NetworkView discovers all TCP/IP nodes in a network, using the following methods: DNS, NetBIOS, SNMP, TCP Ports, WMI and the local ARP table (MAC addresses). It draws a high quality color map of any size that you can print or save for future use. It can also check the status of all or selected nodes with ICMP polling, and send alerts when a system goes down. Eight different lists are available, fully customizable with a list editor.
Requirements:
Windows 2000 Professional, Server or Advanced Server, Windows XP Home or Professional, Windows Server 2003 Standard or Enterprise.
Windows NT 4.0 Server or Workstation with SP6. The Microsoft SNMP service (from CD) and the WMICore 1.5 (downloadable ) must also be installed.
A resolution of 1024x768 or better is preferred
Windows 95, 98, ME are not supported.
Key features:
Floppy and/or USB key usage
The program, including the complete SNMP OID and MAC OUI databases, can be used from a floppy disk or USB key. In fact, NetworkView is composed of just a single executable (~570 KB) and 5 other data files (including the help and license !)
Discovery
Three types of discovery: single address, range of addresses, full subnet. Choice to use DNS, MAC addresses, SNMP, Port scan or analysis, NetBIOS and WMI. Customizable retries and timeouts. ICMP not required to discover behind firewalls.
Powerful map updating using either DNS name or IP address as the permanent identifier, and automatic/interactive removal of obsolete nodes.
***********************************************
I hope this tool can be useful for you.
Best regards and keep the good job.
