Hi @Shad Qadir ,
SQL Server Network Configuration manages the network protocols used by SQL Server instances, applies to the server side, affecting how SQL Server listens for incoming connections.
SQL Native Client 11.0 Configuration manages the network libraries used by client applications to connect to SQL Server, applies to the client side, affecting how client applications connect to SQL Server.
Both configurations need to be properly set up to ensure smooth communication between the client and server. Please restart SQL server instance to make this configuration effect.
Did you install SQL server 2022? Per MS document Get DPM installed, if you plan to use SQL server 2022 with DPM 2022, ensure to install SQL server Native Client (SQLNCLI) on the SQL server machine before you install DPM 2022 RTM as SQL 2022 doesn't ship with SQLNCLI.
