How to identify which destinations are needed for Windows Update RRS feed

  • Question

  • Windows Update and its CDN use an extensive amount of domains and IPs. How can I make sure that Windows Update/Microsoft update is fully functional with a minimal set of allowed Domains/IPs? I had issues like client-update being functional but server-update was failing. Yes, one can use a WSUS and provide full Internet access only to this server, but I'd really prefer to have a whitelisting-based approach.

    I could not find satisfying answers to this yet...
