Terminal Services / Remote Desktop
Making use of WinCron from Remote Desktop is easy.
The basic idea is using the Proxy mode described here .

Quick Start:

1. On the remote system (Server):
   Unregister WinCron as a service (if it is registered):
   C:\Program Files\Tomasello Software\WinCron>WinCron -uninstall
2. Register the WinCron Proxy as a System Service to run in the LocalSystem:
   C:\Program Files\Tomasello Software\WinCron>WinCron -install -proxy
   Or register the WinCron Proxy as a System Service to run in a User Account:
   C:\Program Files\Tomasello Software\WinCron>WinCron -install -proxy -account luket -password rocket_dog
3. (Restart computer or start WinCron Proxy from the Control Panel.)
4. On the local system (Client):
5. Log onto the remote machine via Remote Desktop.
6. From either a DOS prompt or Start/Run,
   C:\Program Files\Tomasello Software\WinCron>WinCron -application –monitor
7. Click on checkbox “Connect to Proxy” to send commands directly to the Proxy WinCron from the Monitor WinCron.

That's it. You now have full command over WinCron running on the remote system regardless of whether it is running in LocalSystem (interactive or not), or a User Account.
When you're done interacting with WinCron, simply close the Client WinCron Monitor and the WinCron Proxy will continue to run.
