While I never really want things to go wrong, I do want to be able to troubleshoot if needed. Probably the tool I use most commonly for that first step is Windows Task Manager. In Windows Server 8, a couple of new things are in place as well as a totally overhauled interface.
If you run Windows Server 8, the Task Manager is still accessible in all of the same ways we’re used to. The Processes tab is one of the first places I go in basic troubleshooting. In Windows Server 8, running processes are categorized into groups: Applications, Background Processes, and Windows Processes.
