A service in Microsoft Windows NT 4 that allows batch scripts to be scheduled and executed using the at command. The Schedule service provides the security context in which the at command can execute the batch files. If you configure the Schedule service to start up using a particular account as a security context, be sure that account is part of the Backup Operators group because the at command is typically used for scheduling backups.
In Microsoft Windows 2000, the Schedule service has been replaced by the Task Scheduler service.
You must start the Schedule service before using the at command. You can start the service by using the Services utility in Control Panel or by using the Net Start Schedule command at the command prompt. The Schedule service is dependent on the Workstation and Server services.
