  • The MID Server throws the error "Failed to communicate with the WMI collector service."
  • The WMI service is struck in starting state.

Check the WMI collector error messages in the MID server logs for further confirmation.

  1. Navigate to MID Server > Servers.

  2. Select the affected MID server.

  3. Under Related Links, click Grab MID Logs.




    1. Stop the service ServiceNow WMI Collector.

    2. Copy the log4net.dll file from c:\windows\system32 to the agent\sw_wmi\bin folder (where the wmi_collector.exe file resides).

    3. Restart the ServiceNow WMI Collector.
    4. Restart the MID Server.

      1. On the MID Server, navigate to Services.
      2. Find the MID Server service and start it.
