IIS won't serve static files larger than 10KB

Hi,

I'm facing a strange issue with IIS on windows 10.

No static files larger than 10KB are served.

Even if I go and try to open the http://localhost/ to see the iisstart.htm page, the iisstart.png is not loaded.

Error in Chrome: Failed to load resource: net::ERR_CONNECTION_RESET (after ~40 seconds of "pending")

No failed requests logged (trying to catch all errors from 401 to 999).

Not a Chrome issue as same happens in FireFox and Edge too.

Tried to reinstall IIS to no avail.

Frustrated. Need help.

Thank you in advance.
