GFI Network Server Monitor is a network monitoring tool of the company GFI. The original source code was bought from a Dutch company ActiveXperts which has its own ActiveXperts Network Monitor. The original source code is written in C++ and uses ActiveX/COM components of ActiveXperts itself. Many similarities in earlier versions of both the products can be viewd in the GUI. Installing the GFI Network Server Monitor on a machine which has already installed the ActiveXperts Network Monitor, can cause DLL conflicts, as many DLL names, and registry entries have remained the same.
As from June 1, 2014 GFI Software™ no longer sells GFI Network Server Monitor and the application has been replaced with GFI EventsManager
