RestoreEncryptionKey Method (WMI MSReportServer_ConfigurationSetting)
Reapplies the specified encryption key to the report server database.
[out] An array containing the encrypted encryption key.
[out] The length of the array returned by the method.
A string used to encrypt the encryption key.
[out] Value indicating whether the call succeeded or failed.
[out] A string array containing additional errors returned by the call.
Returns an HRESULT indicating success or failure of the method call. A value of 0 indicates that the method call was successful. A non-zero value indicates that an error has occurred.
If an entry already exists for the report server in the report server database, it is deleted. The new entry is then created using the specified encryption key and the report server’s public key.
The method is most effective when called after the DeleteEncryptionKey method, which clears the list of encryption keys.
