This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The RemotePassword property specifies a password used when a distributed query, or another Microsoft SQL Server process, accesses a data store using a linked server OLE DB data source definition.
When an OLE DB data source definition, called a linked server, is created, a login record is created that simply passes connection authentication data to the linked server when an attempt is made to establish a connection to the data source.
Configure a linked server definition to use specific authentication data by creating additional records mapping logins on the linking server. For more information about using SQL Distributed Management Objects (SQL-DMO) to configure linked server security, see LinkedServerLogin Object
Creating a LinkedServerLogin object and modifying a RemotePassword property value require membership in either the sysadmin or securityadmin role.
