You can upload an existing KML network link to ArcGIS Server using Manager. This might be a network link file that was created externally, for example, in ArcGIS Earth.
- Open Manager and log in. If you need help with this step, see Logging in to Manager.
- Click Services > KML Network Links > Upload Network Link.
- Browse to the KML network link (.kmz or .kml) and click Upload. The name of the file is used to populate the Name column in the list of network links.
