When you initially load the topology created in the Planning Tool into Topology Builder, you will see a few small, red X error icons, indicating that additional information is required. The information may include specifying the fully qualified domain name (FQDN) for each server in a pool, or updating the name of a SQL Server instance.

Each error must be fixed before you can successfully publish the topology. To fix the error, right-click the node or server, click Edit Properties, and then update the required information. The modifications required are listed in the following table.
