I bought this software package to assist many of my Clients to map out their respective network connectivity as a Values added Services with no charge to them.
Before that, I was using nmap and Zenmap, but NTM gave me more flexibility as it can direct output to MS-Visio.
The first try on a Client network, I faced so many issues like links not found, double or triple links found, etc. Logged a case to Solarwinds and was told that very disappointing feedback "That this product is no longer in development roadmap".
I suggest to relook into this and continue to put effort to make NMTM better. PLEASE.
