WebinarUpcoming Webinar: Know What’s Changed – with NEW Server Configuration Monitor

The configuration of your servers and applications is a key factor in their performance, availability, and security. Many incidents can be tracked back to an authorized (and sometimes unauthorized) configuration change, whether to a system file, configuration file, or Windows® Registry entry. Join SolarWinds VP of product management Brandon Shopp to discover how the new SolarWinds® Server Configuration Monitor is designed to help you.

No interfaces are found in Network Discovery


If the Network Discovery wizard does not find expected interfaces for devices with active interfaces, verify provided SNMP credentials, discovery settings, and devices on the Discovery Ignore list.


All NPM versions


This can occur because of one or more of the following reasons:

  • The SNMP credentials for the devices were incorrect.
  • The Ignore nodes that only respond to ICMP (ping) option under Network Discovery > Discovery Settings view is not selected, and the devices discovered are ICMP-only with no interfaces.
  • The nodes discovered do not currently have any actively operational interfaces.


  1. Verify the following:
  2. Re-run Network Discovery.

See Advanced discovery using SolarWinds NPM for tips how you can optimize discovering your network.
