If your Iguana service won't restart - ServiceErrorLog.txt

If your Iguana service will not restart then a good place to look first is at the ServiceErrorLog.txt file. This will be in the Instance Directory.

For instance I was trying to upgrade our new marketing server today and it failed. When I logged in and looked at the log:

I could see the source of the problem was due to an operating system set up issue it could not listen on port 443. So for that I needed to modify the Web Configuration File - then I could start the server.
