修復用の PowerShell スクリプト

この記事には、お客様が独自のスクリプトを作成する方法を学習するためのテンプレートとして実装または使用できるサンプル スクリプトが含まれています。 修復用のスクリプト パッケージを作成するには、ここに記載されている情報を使用 します。

スクリプトの説明

次の表は、スクリプトの名前、説明、検出、修復、および構成可能な項目を示しています。 名前が Detect で始まるスクリプト ファイルは、検出スクリプトです。 修復スクリプトは Remediate から始まります。 これらのスクリプトは、この記事の次のセクションからコピーできます。

ネットワーク証明書スクリプト パッケージを確認する

スクリプト パッケージは、有効期限が切れているか有効期限が近づいている、コンピューター、ユーザーいずれかの個人用ストアの CA によって発行された証明書を検出します。 スクリプトは、ユーザーにトースト通知を表示することで修復します。

古い証明書スクリプト パッケージのクリア

現在のユーザーの個人用ストア内の CA によって発行された、有効期限が切れた証明書を検出します。 現在のユーザーの個人用ストアの CA によって発行された、有効期限が切れた証明書を削除することで修復します。

古いグループ ポリシー スクリプト パッケージの更新

このスクリプト パッケージは修復に含まれていますが、しきい値を変更する場合はコピーが提供されます。

このスクリプト パッケージは、最後のグループ ポリシーの更新日時が 7 days前よりも大きいかどうかを検出します。 スクリプトは、gpupdate /target:computer /forceと gpupdate /target:user /force を実行して修復します。
