Cannot Delete Subnets from Quality of Service Manager

In the Quality of Service manager, you can add subnets in order to apply policies. However, if you right-click a subnet and then click Delete, you delete only the policies associated with the subnet. You cannot delete the subnet itself.

You cannot delete subnets from this location because they are shared for other options. Since the subnets entries are shared, the Quality of Service manager has no way of knowing what other items will be affected.

To delete subnets:

1. Start the Active Directory Sites and Services Manager from the My Administrative Tools menu.
2. Expand the Sites fork and then expand the Subnets fork.
3. Right-click the subnet you want to delete, and then click Delete.
4. When you are prompted to verify the deletion, click Yes.

This behavior is by design.
