原因：

'SqlColumnEncryptionEnclaveProviders' の構成セクションは定義されていませんが、.NET Sql Client で必要です。

解決方法 1:

まだ存在しない場合は、mssdmn.exeの構成ファイルを作成します (既定では作成されません)。 構成ファイルに次の内容があることを確認します。

mssdmn.exe.configの内容:

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration>
       <configSections>
         <section name="SqlColumnEncryptionEnclaveProviders" 
             type="System.Data.SqlClient.SqlColumnEncryptionEnclaveProviderConfigurationSection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> 
   </configSections>
</configuration>

通常、ファイルは次の場所にあります。

  • SharePoint 2013: C:\Program Files\Microsoft Office Servers\15.0\bin\mssdmn.exe.config

  • SP 2016 および SP 2019: C:\Program Files\Microsoft Office Servers\16.0\bin\mssdmn.exe.config

解決方法 2:

解決策 1 では、検索の問題を解決できますが、他のコンポーネントに関する問題が引き続き表示される可能性があります。 他のコンポーネントに関する問題が引き続き発生する場合は、変更を含むようにmachine.configを変更できます。

次のスクリプトは、変更を自動的に行います。 これは、問題のあるすべてのサーバーで実行する必要があります。
