The '''Name Server Services''' section of the [[Manage_Machines|Manage Machines]] activity lets one start, stop, and check on the background services that run on the name server. The name server is the coordinating Yioop instance whose address is set in the [[Name_Server_Setup|Name Server Set-up]] part of Server Settings; the services listed here run on that instance itself, separately from the queue server, fetcher, and mirror processes shown under [[Machine_Information|Machine Information]].<br><br>

Each service has a row in a table with three columns:<br>

• The '''Service''' column names the service and, where useful, offers icon links to related activities.
• The '''Log''' column links to that service's log file, listing recent entries with the most recent at the top; it is the first place to look if a service will not stay on.
• The '''Status''' column has an On/Off toggle with a color indicator: green when the service is running, red when it is stopped, and a caution color when it was switched on but is not currently running correctly.

The services that can appear are:<br>

• '''Media Updater''' runs the periodic media jobs for this installation, such as downloading feed sources, computing analytics and trending statistics, converting uploaded videos, and sending queued notification email. The icons beside it open [[Configure_Media_Jobs|Configure Media Jobs]], where one chooses which jobs run, and [[Media_Sources|Media Sources]], where one manages feed and search sources; see [[Media_Updater|Media Updater]] for a fuller description. When the media updater is run in distributed mode, the status shown here is only for the copy on the name server.
• '''Mail Server''' appears only when '''Mail Services''' in the Server Settings activity is set to use Yioop's own MailSite server rather than relaying through an outside mail account. It runs that built-in mail server, which carries outgoing messages such as registration mail and thread notifications. Its log and On/Off toggle behave the same way as the media updater's.

Turning a service off here stops it on the name server, and turning it on starts it. A service that starts and then stops on its own usually records the reason in its log.<br><br>
