ISubscription Interface

  • 项目

 

Applies To: Windows Server Update Services

Used to view or modify the synchronization settings and to start the synchronization process manually or automatically. Downstream servers receive synchronization settings from the upstream server. Downstream servers can modify and save synchronization settings; however, only the synchronization schedule is used by the downstream server. WSUS ignores the other settings. Downstream servers can also start and stop the synchronization process. To retrieve this interface, call GetSubscription.
