AFAIK You can safely ignore these
for ex:
1)Error No application is using IIS Secured(System)'s configured port 443 with a state of 'Listen'.
SEP 12.X does not use IIS
2) Error No application is using RADIUS Communication(httpd.exe)'s configured port 1812 with a state of 'Listen'.
-> only when you have Enforcer
3) just saying that no one is using that configured port.
