The Set the SMTP Server used to send notifications machine setting should be configured correctly. This setting assigns the address of the SMTP server that sends out notifications. If you enable this setting, Windows System Resource Manager (WSRM) will set the SMTP server to the value specified. If you disable this setting, no SMTP server (default value) will be set. If you do not configure this setting, the user may specify an SMTP server. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows System Resource Manager\Set the SMTP Server used to send notifications (2) KEY: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\WSRM\SMTPServer
