aspnet_regiis section not found

i'm trying to encrypt my web.config. aspnet_regiis keeps telling me: The configuration section 'applicationSettings' was not found. I followed this site: Walkthrough: Creating and Exporting an RSA Key Container My web.config looks like this: ``` <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="x" type="x" /> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <section name="x.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <configProtectedData> <providers> <add name="MyProvider" type="System.Configuration.RsaProtectedConfigurationProvider, System.Configuration, Version=2.0. 0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" keyContainerName="MyKeys" useMachineContainer="true" /> </providers> </configProtectedData> ... <applicationSettings> <x.Properties.Settings> <setting name="PollingInterval" serializeAs="String"> <value>10000</value> </setting> </x.Properties.Settings> </applicationSettings> </configuration> ``` I use the command: aspnet_regiis -pe "applicationSettings" -app "/MyApplication" -prov "MyProvider" When I move the Section configProtectedData above the configSections it encrypts the applicationSettings, but removes the configSections-Section, anyway, IIS tells me configSections need to be the first element. I'm not sure what I'm doing wrong. Is it a problem, that the applicationSettings is listed in the configSections? Thank you for your help.
