Caspol

Question

I have an application that should run on a shared folder in a network(domain).
when each user tries to run that,they see the error message indicating they have not the permission to access the sql server(don't have SqlClientPermission).
I don't want to instruct every user to manually run the caspol.exe to add a group with fulltrust permission under LocalIntranet CodeGroup.
how can I place that in my code?
