.NET Winforms Secuity Issue - Deployment

[None]

I am getting security exception when I try to access any network
folder or database or when I am trying to create a file on the network
share using my .NET Windows application. I know I can make it to work
from my machine making the code FULLTRUST.

What I need to know is how I would be able to make the application
work across the network from all machines without using the .NET
configuration utility or making it as a package may be using a batch
script?

Any help is greatly appreciated.

Thanks
