Encrypting Web Config using ASPNET_REGIIS

I need to encrypt certain parts of web config. After reading some tutorials I have learned that using the tool ASPNET_REGIIS is the way to go. This is what I am trying at the moment: From the Command Prompt ``` ASPNET_REGIIS -pef "identity" "D:\IIS\admin.mySite.com" ``` "The configuration section 'system.web\identity' was not found." ``` ASPNET_REGIIS -pef "system.web\identity" "D:\IIS\admin.mySite.com" ``` "The configuration section 'system.web\identity' was not found." ``` ASPNET_REGIIS -pef "system.web/identity" "D:\IIS\admin.mySite.com" ``` "Failed to encrypt the section 'system.web/identity' using provider 'RsaProtectedConfigurationProvider' Error message from the provider: Object already exists." To try and see if am getting anything right I tried the following: ``` ASPNET_REGIIS -pef "connectionStrings" "D:\IIS\admin.mySite.com" ``` "Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider' Error message from the provider: Object already exists." ``` ASPNET_REGIIS -pef "connectionStrings" "D:\IIS\admin.mySite.com" ``` "Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider' Error message from the provider: Object already exists." ``` ASPNET_REGIIS -pef "DoesNotExist" "D:\IIS\admin.mySite.com" ``` "The configuration section 'DoesNotExist' was not found." Help!
