Enable Scheduling and Delivery Service For SSRS

While I was working in a SSRS project i had to spent two days why scheduling and delivery process is not working in the report server.Then I found the following thisng in msdn which helped be to get rid of this problem.

Set the following values to TRUE in rsreportserver.config file.

1. IsSchedulingService
2. IsNotificationService
3. IsEventService

In my case these values had been set to False.
