The ArcGIS Server Services Directory is a RESTful representation of all the services running on your ArcGIS Server site. One of the links in the Services Directory allows you to preview a service in Map Viewer Classic. You can configure the Services Directory so that this link displays the service in your own portal's Map Viewer Classic instead of the ArcGIS Online Map Viewer Classic.
- In a web browser, open the ArcGIS Server Administrator directory and log in with an account that has administrative privileges to the site. The Administrator Directory is typically available through a URL such as https://gisserver.domain.com:6443/arcgis/admin. If your server is federated with the portal, see Access the Administrator Directory on a federated server for more guidance on how to log in.
- In the Administrator Directory, click system > handlers > rest > servicesdirectory > edit.
- In the ArcGIS.com URL box, type the URL to your portal's Map Viewer Classic, for example, https://webadaptorhost.domain.com/webadaptorname/home/webmap/viewer.html
- In the ArcGIS.com Map Text box, type a label for your Map Viewer Classic URL, for example, ArcGIS Enterprise Map Viewer .
- Click Save.
