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

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.

Updated August 2, 2016

Overview

This article provides brief information and a resolution to the issue when the following event appears for a device that is already managed, but by a different IP and the Netflow IP:

Resolution

Any of the following can resolve the issue:
