Интересный момент. Пытаюсь создать домен с определенными правами на запуск кода (добавил все 26). Пытаюсь запустить сборку -- выдает ошибку "That assembly does not allow partially trusted callers". Чего бы еще добавить, чтобы оно запускалось? Самое интересно, с сетевого диска эта сборка запускается без проблем...

Вот такие пермишенсы есть:

PermissionSet permissionSet = new PermissionSet(PermissionState.None);

            permissionSet.AddPermission(new System.Data.SqlClient.SqlClientPermission(PermissionState.Unrestricted));
