Hi all,

I have written an Win Forms applicaiton that is used to encrypt various web configuration files with RSA - making use of Microsoft Server 2008. The thing is that I have receive the following exception when trying to opne the configuraiton file (I am not making use of the Default Web site) - on the following line in the code:

Configuration config = WebConfigurationManager.OpenWebConfiguration("/", "SiteName", null, Enviorement.MachineName);

The strange thing is that it works on another Microsoft Server 2008 machine (Testing enviorement), but the clients Server gives the exception.

I have looked at the following web sites (WebConfigurationManager.OpenWebConfiguration() - Failed to resolve the site ID
[^]) but did not provide an answer.

Could anyone please help me?
Many thanks in advance.
Kind regards,
