You might get an annoying event log error, if you server does not have a direct connection to the internet (no internet at all, or some ports are just blocked). That’s because your computer is trying to get root certificates update from Microsoft. You use those for Internet Explorer browsing. But who cares about browsing on a server? This is how you can disable root certificates update, and get rid of false errors in the event log:
Control Panel > Add/Remove Programs > Add/Remove Windows Components > Update Root Certificates (clear check box), continue with uninstallation.
