We are using Azure VM network, and would like to know if/how we could get windows NLB to work with them, the internet is sparce on the list of compatabile software of windows NLB as of now it appears, and the only answer we could find was an unofficial one stating it is not possible. I would like to know if its possible to confirm or deny that.

    Hello

    Its not supported unfortunately, but you can use the Azure Load Balancer to get the results you want. Check out this link for information on Azure Load Balancer

    https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-overview

    For the official statement of not supported check out this link. Scroll down to the "Windows Server Features" section.

    The reason why its not supported is that you cant utilize broadcast or multicast on layer two in Azure.
