System.Security.SecurityException

[Guest]

Hi.
I have my program written as a console application in C# .NET 2005.
I run it from a server on the local intranet and I got this message:
An unhandled exception of type 'System.Security.SecurityException' occurred
in System.Data.dll

Additional information: Request for the permission of type
'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I tried to set the security permissions.
My manifestfile look like this:

<?xml version="1.0" encoding="utf-8"?>

Can anyone help me with this?

Requesing a permision does not mean it will be granted. I think you
should grant the assemply sufficient permissions. Check out the .net
util in Control Panel.

Thanks for the answer.
I haved tried to change the permissions in Microsoft .NET Framework 2.0
Configuration but with no success.
Can you give me a hint?
