A question I see a lot has to do with running multiple websites on a single web server. This is a relatively simple topic once you are able to grasp one concept: website bindings. Every website on a server needs to have a unique binding. There are three parts to a website binding, the IP address, the port, and the host name.
I was troubleshooting an issue today using Failed Request Tracing (FREB) and I kept getting LOG_FILE_MAX_SIZE_TRUNCATE before I could find the root cause of the issue. I came across a post with information on how to change the default size of the FREB log file and find the issue.
