Previously, the Windows agent controller used TCP-IP as a channel to local Windows agent, but this type of communication can lead to port conflicts. Also, mailslots inherently provide slightly better level of local security.

If, for some reason it is required to use TCP-IP as a channel, you may set system.controller.agent_channel in the check_mk.user.yml to any appropriate value, for example, "localhost:28250".
