    Hi Shiva

    Thanks for great on Hot-to document.
    Question: If you using external certificate Authority such as Go-Daddy, Comodo etc.. We have certificate-chain such as Root, Intermediate and Server certificate. If server certificate Link to Intermediate Cert.
    Should i also Link intermediate cert to Root CA as well?

      when we import the pfx file which has all the links, it will install the certs. always recommended to link them cert to intermediate to root.
