SqlServerAlias Class
Applies to: 
SQL Server
The SqlServerAlias Class class represents a server connection alias.
A server connection alias is required when both the following occur:
The client is connecting to an instance of Microsoft SQL Server over a network transport that is not the default network transport.
The instance of SQL Server to which the client is connected listens on an alternate named pipe.
Note: The SqlServerAlias Class inherits the Put method from the Provider class. However, it does not return any results as indicated by the Provider::Put method. For more information, see the WMI documentation.
