Cause

This issue can occur when the WinPcap driver is corrupted or the NetPath time is set to lower than 5 minutes
 

Resolution

If you have issues with the WinPcap then there are two ways to resolve this issue, depending on the server where WinPcap needs reinstalling:

Resolution1
If error is shown on the Orion server, do the following:
  1.  Temporarily disable any antivirus programs.
  2. Use the Orion Service Manager to stop all Orion services.
  3. Open C:\ProgramData\Solarwinds\Installers and find the file(s) with names starting: WINPCAP
  4. Right-click on the newest file and click Uninstall. When the uninstall completes, double-click the file to reinstall
  5. Start and run Configuration Wizard
Resolution 2
If error is shown on an Agent server (not an Orion server), do the following steps:
  1. Stop the Agent service (Run services.msc > Stop SolarWinds Agent)
  2. Uninstall WinPcap (if it's there)
    • If you can't uninstall, try to restart the target machine.
  3. Reinstall WinPcap
  4. Restart SolarWinds Agent

Resolution 3
- Set Probing Interval to 10 minutes

Note:
 The probing interval can be increased or decreased, but 10 minutes is the recommended starting probing interval for NetPath. Please update the probing intervals, wait an hour and check again.
