      Did a firewall setting get changed?

      Is this a public facing website?

        No, will face into the LAN only. It's just for internal use. And I am only testing from the local machine right now, and even that is not working.

          No, it is centrally controlled via GPO. Nothing has changed. And I am testing using the loopback which should not hit it and did not hit the firewall before. And HTTP is allowed through it, too.

            Is this just a basic HTML website? It sounds like you just have a hung service.

              He stated it was an application. First post wasn't that far up.

                    A 503 means that IIS is responding but that there is an error. Here are the possibilities for the error code: https://technet.microsoft.com/en-us/library/cc781893(v=ws.10).aspx

                    Because a 503 and not a "Page Cannot Be Displayed" error is what is coming through, it sounds like we are past the Firewall point and are dealing with something wrong with IIS configuration not Firewall. This implies (I think) that port 80 is making it through end to end to deliver the error code.

                        It's a small semi-custom thing that we have run for years but is being moved to a new server.

                          By default all sites should log here: %SystemDrive%\inetpub\logs\LogFiles

                            Wait 2.0? Did you properly configure the pool? Gimme a minute and I can log into a Server 2012 R2 with IIS running.

                              This is the application pool. You may also need to select classic pipeline mode.

                                No, only certain that I didn't find anything logged 🙂 I'll check again.

                                  Yes, very old. And I "did" have it configured properly, it was running fine before the reboot. So at least at some point it was working as it should.

                                    @JaredBusch ah ha, there we go! The 2.0 pool had "stopped" for some reason. I started it and the site came up. Thanks!

                                      There were two application pools, one for 2.0 Integrated that was running, and one for 2.0 Classic which had stopped. Classic was the one that was needed.

                                        If you click on Basic Settings for your application it tells you which pool it is using.

                                          Well I thought that we were good. I started the pool and the site came up. Went to refresh the page and it is down again with the same 503 error again.
