ASP.NET 2.0, WSS 3.0: a ASP.NET App in Folder of WSS 3.0->Sec.Exep

[=?Utf-8?B?U3ZlbiBXLg==?=]

Hi Newsgroup,

i have the following enviroment. On Windows 2003r2 I have

- WSS 3.0
- .Net Framework 2.0
- MSSQL 2005 Developer

This is running fine. Besides the WSS I have a small web (asp.net)
application that is accessing the MSSQL 2005 and displaying some crystal
reports. This application is doing fine, aswell.. as it is running as a
different "Website"

But.. I want to move that small application to run as a virtual directory
within the WSS folder.

WSS: http://<dns domain name of server>
Asp.Net application: http://<dns domain name of server>/applicationfolder

when I run the application from the upper shown path, it throws an exeption:

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

outerConnection) +22
System.Data.ProviderBase.DbConnectionClosed.OpenCo nnection(DbConnection
outerConnection, DbConnectionFactory connectionFactory) +105
System.Data.SqlClient.SqlConnection.Open() +111

Why does the application in its own website, but not inside the website of
WSS ?!!

Thx in advance,

Sven
