We recommend connecting the PCs in a network by using i.e. a rooter. In case a rooter cannot be used and two PCs are connected via a cable, consider the following remarks:

  1. Establish a network by cable.
  2. By default, a network/connection is established.
  3. As a test, check the IPs of the computers and ping each other.
  4. In case this fails, check the ethernet adapter and enable DHCP. Also check firewall notifications/settings.
  5. Ports used by ZEN are open by default, but could be blocked by various reasons (IT, Windows, firewall).
  6. If a port is blocked. try to set another port in the ZEN options for Direct Processing (see also the help for ZEN).
  7. You can also test more than one ethernet adapter by pinging the PCs.
