I do not have much firewall configuration experience and need help in this case:
Got a situation where there are 3 servers: 1 is a DC/Exchange, 1 is a Terminal Server, and 1 is an application server.
Windows firewall is off on all 3.
When I enable Windows Firewall in the DC/Exchange, I just use the default settings, without changing anything: domain users are unable to do anything on the network.
What ports should I open to at least get them started and then take it from there?
