NTM stops responding and fails with an application error when attempting to load an existing map or at the end of a discovery when a map is being drawn.


  • NTM v2.2.1 and previous versions
  • Any version of Windows with .NET Frame 4.6


This issue is due to the fact that NTM v2.2.1 is attempting to use a .NET function which is no longer supported in .NET 4.6.


Download and apply SolarWinds Network Topology Mapper version 2.2.1 Hot Fix 1.
