I and the interesting experience watching an overzealous VP in charge of "Project Capture" implement some of these tools for tracking, inventory, and cross-referencing.... The final solution, for all but configuration management, was (as Hugh mentioned) Nets. It was the most configurable and dynamic. But here you're not looking at an "out-of-the-box solution, and if the network is large enough, you'll require a small team of people to run it. Personally, I like a simple CVS system for config files, a separate system. <fighting urge to go on pro-opensource rant> There are several quality commercial products out there. Lucent for example, in their Vital* platform, does do everything but cook you breakfast, but for the price should. Adding to the list for IP Allocation and DNS management would be NameSurfer by Nixu. -- sig=$header
