In an environment where you have a decent amount of live and servers it is very time consuming ensuring that the relevant Dev/QA environments have the same server level settings as live.
Having a tool that allows server level settings to be exported as one file and loaded onto another server to ensure consistency would really help. this could be as simple as an XML file with server settings embedded.
This would also help with questions posted to online help forums in order to help diagnose a problem. How many times do you see various settings being checked remotely where one file that had all of these settings would get the issue out in the open right away.
