In a lot of situations we may not have permissions to use SQL Server Agent for automations of our back-end processes. I built a run-around that uses a Windows Scheduled Task, SQLCMD and Stored Procedure to run task.

Work flow:
1. Windows Scheduled Task calls a .bat file at specific reoccurring time
2. .bat file executes SQLCMD
3. SQLCMD creates a connection to SQL Server and executes the SP

Scheduled Task

SQLCMD

Stored Procedure

Warring: If the connection between the machine that triggers the Scheduled Task and the SQL Server is interrupted during the execution of the SP, it does not end.

Keep it simple :-)
