Parser Error Message: Failed to decrypt using provider 'WSConfigProvider'. Error message from the provider: The RSA key container could not be opened.


Im trying to copy a website from one server to another, however I am getting the error above

<connectionStrings configProtectionProvider="WSConfigProvider">
Line 51: <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"
Line 52: xmlns="http://www.w3.org/2001/04/xmlenc#">
Line 53: <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc" />

I have copied the entire site so cant think what file it could be missing, however looking at the article http://msdn.microsoft.com/en-us/library/ff650304.aspx
I cannot seem to find the location Documents and Settings\{UserName}\Application Data\Microsoft\Crypto\RSA on the server, where would this be on a 2008r2 server? And is there some files in there missing which could be causing this error?

On further reading it looks like im better off just replacing the encrypted data in the web config and re-encrypting them on the new server.
