Troubleshooting: "Server extension failed during setup: RxEventServerExtension"

This error is written to the Responder Data Services console (DataServices.exe) when it is launched.

Problem: An invalid multicast address was provided in the DataServices.exe.config file.

Fix: Add a valid multicast address by following these steps:

  1. Open DataServices.exe.config located at Program Files\Miner and Miner\Responder\Server.
  2. Scroll to the <miner.responder.server.configuration> tag.
  3. Find your current server configuration and then look for “multicast group =” (highlighted in the example below). This multicast group value must be corrected.
  4. Type a valid IP address.
