On a computer that is running Windows 7 or Windows Server 2008 R2, the network location profile that is selected changes unexpectedly from Domain to Public. Additionally, the firewall settings (these are determined by the network location profile) change to the settings that correspond to the Public network location profile. Therefore, some outgoing connections may be blocked, and some applications may be disconnected.
