IOPermission while saving configuration file

In a windows form app (2.0) I get an IOPermission failed while
executing the lines:

Configuration exeConfig =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
// ... add one item
exeConfig.Save(ConfigurationSaveMode.Modified);

The exeConfig resides on a network share. When I configure
'unresctricted access' on the network share it works, however
'RW,append+path disc. permissions configured on that share or even on
the exact file, does not work.

How does it work?

Could you please post the full exception details (including call stack
listing), as returned by its ToString method?

Thanks for your support, here follow the exception details:

--
A first chance exception of type 'System.Security.SecurityException'

The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.Permissions.FileIOPermission
The Zone of the assembly that failed was:
Intranet
--
I was surprised to discover the last two lines 'Intranet Zone', because
I configured a special code group with the URL membership condition
\\myserver\myshare\*. If more than one union code group matches, the
combination of their permission sets is granted.

So what should I do to let it discover my special code group?

Thanks.
