Multiple issues with TestStudio

Hi

I need to test a desktop windows based application which is developed using .net 4.0, Telerik RadControls for WinForms 2010 Q3, Infragistics Controls for Winforms. I need to perform regression tests for this application.

Issues:

1. I work on one domain say X but my applications works on another domain say Y so what I do to run my application on X domain I use run as and give the Y domain's credential and open my application test. My problem here, to record actions in TestStudio I need to give the .exe path and perform some actions. Actually to run my application I have to give Y domain's credentials using run as but when run the actions it tries to open the applcaition directly. Here it fails to open the application itself.

2. To avoid above problem, I tried to work from Y domain itself but here one more problem. 

        Here there are sequnce of actions:
                i. Open the application
                ii. Click on tree node to open folder which is much similar to Windows Explorer (I think this is developed using Infragistics Controls)
                iii. Open a Time series chart from that folder (Which is developed using RadControls)

After stoping the recording and run the actions, here I have one real problem. It just opens the application but doen't perform any other actions.

Please give some solutions to resolve these issues,

Thanks,
Sri
