Basic認証を許可

現在のAnsibleは、Basic認証を前提に開発されていますので、Basic認証を有効にします。

PS C:UsersAdministrator>winrm set winrm/config/service/auth '@{Basic="true"}'
Auth
    Basic = true
    Kerberos = true
    Negotiate = true
    Certificate = false
    CredSSP = false
    CbtHardeningLevel = Relaxed

HTTPでの接続許可

PS C:UsersAdministrator> winrm set winrm/config/service '@{AllowUnencrypted="true"}'
Service
    RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)(A;;GR;;;IU)S:P(AU;FA;GA;;;WD)(AU;SA;GXGW;;;WD)
    MaxConcurrentOperations = 4294967295
    MaxConcurrentOperationsPerUser = 1500

    MaxPacketRetrievalTimeSeconds = 120
    AllowUnencrypted = true
    Auth
        Basic = true
        Kerberos = true
        Negotiate = true
        Certificate = false
        CredSSP = false
        CbtHardeningLevel = Relaxed
    DefaultPorts
        HTTP = 5985
        HTTPS = 5986
    IPv4Filter = *
    IPv6Filter = *
    EnableCompatibilityHttpListener = false
    EnableCompatibilityHttpsListener = false
    CertificateThumbprint
    AllowRemoteAccess = true

HTTPS 有効化

HTTPでも暗号化して送信される為、プライベートなサブネットで特に問題はないかもしれませんが、通信路の暗号化を行うことにします。
証明書とか作るのも面倒なので、以下のスクリプトでザクッと作成してしまいます。

スクリプトは以下のものを少し修正しました。
