install on new 2019 server - post installation tasks fails: HTTP status 503: Service Unavailable RRS feed

  • Question

  • I have a 2019 server (new clean install) and am trying to install wsus from the server manager gui.

    All goes well until post installation tasks and I get: "Fatal Error: Failed to start and configure the WSUS service"

    When I look at the log I see (amongst other things):

    2019-08-16 09:47:33  CreateDefaultSubscription failed. Exception: System.Net.WebException: The request failed with HTTP status 503: Service Unavailable.

    2019-08-16 09:47:33  Microsoft.UpdateServices.Administration.CommandException: Failed to start and configure the WSUS service

    Any ideas?

  • Hi Roga,

    The solution is very simple. 

    Go to the IIS Console on your WSUS server
    Delete existing WSUS Administration site
    Reinitiate the post-instalation task.
