SolarWinds N-central servers becoming unlicensed

A SolarWinds N-central server will become unlicensed by design if the server is moved, restored, or hardware is changed. This is by design for copy protection and avoid illegal software distribution. If a server is becoming repeatedly unlicensed, it can be for the following reasons:

  • The mac address has changed on a virtual machine, such as dynamic mac (Hyper-v), vMotion/dynamic hosting (VMWare).
  • The System UUID has changed because of new hardware or a new virtual machine.
  • You restored a snapshot.
  • There was a change in the network hardware settings.
  • The licence length expired. For new partners: If you have only used the temporary license key received in an email, you need to open ports 22,80,443 & 10000 inbound to SolarWinds N-central, and contact Technical Support with your public IP/FQDN for a permanent license.
  • The server was powered off for a period of time.
  • You upgraded SolarWinds N-central .
