OLEDB Encryption uses Secure Sockets Layer (SSL) encryption to encrypt communications between clients and a SQL Server named instance. You can use this method to encrypt data flowing between the Management Server and the MOM Database Server or between the Database Server and the Reporting Database. You must have a server certificate to enable this method. For more information about using OLEDB Encryption with SQL Server 2000, see the SQL Server 2000 Books Online, or article 316898, "How To Enable SSL Encryption for SQL Server 2000 with Microsoft Management Console," in the Microsoft Knowledge Base.
Enabling OLE DB encryption for SQL Server enables it for all communications with the particular named instance of SQL Server for all clients.
