Cause

This problem occurs because the connection through WMI also verifies the connection information through a reverse lookup on the hostname IP to ensure it is correct. If there are no reverse or PTR records or the records exist but are incorrect, then the WMI connection will resolve to the wrong IP or not resolve to an IP connection.

Resolution

This is an environment issue and must be confirmed in your network. SolarWinds recommends verifying that the records for that hostname and IP are correct and working properly. Once they are added or corrected, then the WMI connection will be able to resolve through WMI correctly.
