Ports Question AEM 6.3

[learn700]

Getting error message port already use for port 8443 and 443 when configuring ssl.

Ports 8443 and 443 are they already used by AEM by default?  Is there a way to check it?  

Thanks in advance.

You can check which process is using your ports as mentioned here networking - How can you find out which process is listening on a port on Windows? - Stack Overflow

AFAIK AEM does not preoccupy any port other than the port in which it is registered .
