Handle Remote Desktop Idle timeout

Hi, 

We want to use RDP for connecting to remote machine, execute Desktop Application Automation there. The challenge that we face is that on the customer end there are restrictions on idle timeout in RDP session. Once we start executing the automated desktop application and if execution takes longer that than the idle timeout to execute, the remote desktop session ends, and the Desktop Automation fails. Is there a way to handle this?

1. I have tried TSCON, but TSCON unlocks the console session, so it may not be acceptable to customers.

2. I have also tried Java's Robot classes to do some mouse action(https://stackoverflow.com/questions/52874/how-do-you-keep-the-machine-awake) This also works with limited scope. In case the RDP session loses focus, it does not work.

Is it possible to keep the RDP session from disconnecting on Idle Timeout?

Thanks in Advance.

Best,

Sumit
