Windows Firewall struggles to recognize a domain network (or detect the changes after a computer connects to a domain network) because of inconsistencies in the network path or setup.įor example, VPNs have something to do with Windows Firewall’s inability or failure to recognize domain networks because their clients tend to add routes to the domain network and this causes some sort of delay. Net Why doesn’t Windows Firewall recognize my domain network? In many of those scenarios where things did not go as expected, users were using a third-party virtual private network (VPN) to connect to the domain network – and this might explain one or two things. However, it sometimes happens that Windows Firewall ignores the changes in network configuration or refuses to recognize the new domain. When a computer gets connected to a domain network (for a company, for example), Windows Firewall switches to a domain profile automatically – or at least, in theory, Windows Firewall is supposed to do that.
