System.Security.SecurityException: Request failed.

[PureMorning]

Im trying to place a C# app for updating a sql database directly on the server and executing the app over the web but when I try it out I get the following exception. It works fine when I run it off my PC. Also, you can type this url in to get the program error directly: http://www.directaccesslegal.com/dals/DALS_Update_App.exe
any help would be greatly appreciated.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

By default .Net apps running from a network have more restrictive permissions - either run it locally or look at the configuration tools to increase the permissions.
