For instances where the IIS is malfunctioning, the website of a Trend Micro product like OfficeScan may not work properly or even stop working.
Reinstalling IIS will fix this but you will lose all the settings and configurations of all the websites under IIS. You need to back up all the settings and configurations and restore it after reinstallation.
