Well, the post pretty much answers itself. Without an 'entire network' object/container, all nodes end up being bound/binded to Infrastructure Services.
So... Also wrote a script (first draft, you should optimize this or add it to another Hook:: script for efficiency) to block unwanted auto-discovery networks. This tremendously helps anyone create Layer-3 IP generated NetXMS Maps by removing 'common' subnets such as 192.168.88.1 or 192.168.20.1 or 169.254.0.1 etc..
So Here's the script, it does a few simple things but most importantly removes any 'unwanted' networks from the 'Entire Networks' container/zone
How can this script be improved? Should it exist in configuration? Or in Hook::AddNode? (is that it?)
It's been hand edited/cleaned up, and untested.. so please don't run this on production without reviewing everything it does.
