Osservazioni

The computer running the instance SQL Server might not receive responses to the EnumAvailableSqlServers method in a timely manner. The returned list might not show all the available instances of SQL Server on the network. When you call the EnumAvailableSqlServers method in subsequent tries, more servers might become visible on the network.

This method fails to list the local instance if a firewall is operating on the server. The firewall blocks any broadcast traffic issued when the method is called, even if the sender is from local machine.
