I was getting a similar error when I was accessing a file on the local intranet. I changed the framework security settings and the problem went away.

Control Panel - Administrative Tools - .NET Configuration - Configure Code Access Security Policy - Adjust Zone Security

Go there and adjust your settings as needed. I hope this helps.
