Замечания
The RemoteServer object exposes the attributes of an instance of Microsoft SQL Server known as a remote server to another server. A LinkedServer object exposes the properties of an OLE DB data source (linked server), allowing Transact-SQL queries against defined data sources.
Use the SetOptions method to set attributes for a remote or linked server.
