Following are frequently asked questions – and answers to those questions – for QoS Policy.
What operating system does my domain controller need to be running to use QoS Policy?
Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008
What operating systems support the application of QoS Policy to the user or computer?
You can apply QoS policies to users or computers running Windows Server 2016, Windows 10, Windows Server 2012 R2, Windows 8.1, Windows Server 2012, Windows 8, Windows Server 2008 R2, Windows Server 2008, and Windows Vista.
Do QoS policies apply to the sender or receiver of traffic?
QoS policies must be applied on the sending computer to affect its outbound traffic. In order to affect the bidirectional traffic of two computers, QoS policies need to be applied to both computers.
What happens if conflicting QoS policies are deployed to the same computer?
If multiple policies apply, the more specific QoS policy takes precedence. For example, a policy that states a host address (192.168.4.12) gets applied instead of a less specific network address (192.168.0.0/16). If a computer-level and user-level policy have the same specificity, the user-level QoS policy is applied instead of the computer-level QoS policy.
