Hi everyone. I'm creating an app that stores DB connection strings in the
web config file. I'm using the MSDN resources at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secmod/html/secmod21.asp and the related articles for help.

However, when using the code in the above article, I get the following
exception:
"Exception decrypting. Unable to load DLL (kernal32.dll)." When I click on
the button "Decrypt string from config file", the application begins to
postback but then quits after the Page_Load event.

If someone could point me in the right direction, it would be very much
appreciated.

Hi Mark,
You check the config file settings. If everything finds right there, please
check the security settings for the dll.

The only change that I made to the web config file was the one that the
article suggested that I make. That is, add the appSettings section.

With regard to the security settings for the dll, what should they be?
Also, please specify what dll that you are concerned about. This application
was created and then built in VS 2003 just like all my other apps. What now
would make VS alter an app's security settings? Does Windows XP SP2 have a
hand in this?

Thank you for your help in this matter.
