Commenting out entries in services only removes the port to service name mapping for a service. It doesn't prevent traffic on the port.

If you want to block traffic you need a firewall. You can easily configure a firewall to block selected services completely. Some firewalls (WinRoute Pro does this) allow you to block ports on a schedule. For instance, allow ftp during the day and block it after hours.

If you don't want services your server provides to be available (such as incoming telnet, ftp, etc.) you need to disable them in the service control panel or uninstall them in the network control panel.
