I then logged into a Windows 7 computer on the LAN and added a port allowance to test telnet from the servers. I still cannot telnet to the port and netstat -ano still does not list it as listening. On the new 2016 server forced a group policy update and saw the test port allowance added in the firewall GUI. As a test, I added a port there "Test GP" No group policies are turning the firewall on or off, though the default Windows Firewall Policy (on the old SBS 2011 server) has three explicit inbound allowances for remote event log management. I have proven that with the firewall enabled, advanced options are to allow inbound connections on Domain and Private connections, the 2016 server still does not list the desired ports as listening and does not respond on them to telnet. I've wracked my brain on this and am not finding solutions anywhere. Logs are not reporting any activity on the manual ports. Windows Firewall has been tested both on and off on all zones, with the service running and disabled with reboots between each configuration change. No group policies are forcing settings related to firewall. I am logged into the server as a domain admin. Netstat -ano on the 2016 server does not show the added ports as listening. Telnet across the LAN to port 139, which is open by default for file sharing, opens. The rules show up as active and enabled in the Advanced Firewall configuration and can be found in the registry. Since the primary port was not working, have since tried manually adding others. In troubleshooting, Webroot has been removed until this works. It reported no alerts with the agent installation. Webroot antivirus had originally been installed because it has not proven problematic on other systems. No remote access has yet been configured. It's currently serving DNS and DHCP, but that's it. The server is joined to a domain as a member.

In most cases on previous server versions, the agent install creates a firewall allowance that works. Trying to configure a backup appliance that needs to communicate over the LAN on a handful of ports.
