Does iis keep track of when last it was reset
Like for other Windows services, the Service Control Manager (SCM) keeps track of service restarts on the System Log of the machine. Please take a look at the Event Viewer to see them.
- Open Event viewer, navigate to "Windows Logs" -> "System"
- on the right "Actions" pane, select "filter Current Log..."
- Under "Event Sources:" select or type "IIS-IISReset"
- hit ok
Results in event viewer should now just show you IIS Resets
