The Set up a maintenance schedule to limit the maximum network bandwidth used for BITS background transfers machine setting should be configured correctly. This policy setting limits the network bandwidth that Background Intelligent Transfer Service (BITS) uses for background transfers during the maintenance days and hours. Maintenance schedules further limit the network bandwidth that is used for background transfers. If you enable this setting, then you can define a separate set of network bandwidth limits and set up a schedule for the maintenance period. You can specify a limit to use for background jobs during a maintenance schedule. For example, if normal priority jobs are currently limited to 256 Kbps on a work schedule, then you can further limit the network bandwidth of normal priority jobs to 0 Kbps from 8:00 A.M. to 10:00 A.M. on a maintenance schedule. If you disable or do not configure this policy setting, then the limits defined for work and/or non-work schedules will be used. Fix: (1) GPO: Computer Configuration\Administrative Templates\Network\Background Intelligent Transfer Service (BITS)\Set up a maintenance schedule to limit the maximum network bandwidth used for BITS background transfers (2) KEY: HKLM\Software\Policies\Microsoft\Windows\BITS\Throttling\EnableMaintenanceLimits
