You are configuring common GPO properties for folders. You want to only specify that only portable computers that are docker have a preference applied.

Explanation:

Configuring Processing Order and Precedence

Multiple Group Policy Objects (GPOs) can be linked to the same site, domain, or organizational

unit (OU), and OUs inherit GPOs from higher-level containers. GPOs are processed serially, with

local computer Group Policy processed frst. Inherited GPOs are then processed, unless they

are blocked or enforced (see the sections entitled "Confguring blocking of inheritance" and

"Confguring enforcement of inheritance" later in this chapter). The GPOs linked directly to the

domain or OU are processed in the order they are linked; then enforced GPOs are processed.

Where multiple GPOs are confguring the same Group Policy setting, the last one processed

controls the setting. You can control the order of linking for an OU or domain, as well as controlling inheritance to some extent. You can block inheritance at the domain or OU level, but

where the higher-level link to the GPO is set to Enforced, the inheritance can't be blocked and

enforced links are the last processed—again, in the reverse link order.

To see the order of linked GPOs, use the Group Policy Management Console (GPMC).

Select the domain or OU for which you want to see the link order in the console tree, and

then select the Linked Group Policy Objects tab in the details pane, as shown in Figure 6-1.

To change the link order, select a link in the Linked Group Policy Objects pane and then

use the arrow buttons on the left to move the order up or down, as desired. Move a linked

GPO to a lower Link Order number to have it processed later. Thus a GPO with a Link Order

of 1 will be processed after a GPO with a Link Order of 2; and if both GPOs have a policy confguration for the same setting, the GPO with a Link Order of 1 will be the controlling GPO.

Remember that policy settings can also be inherited. To see all the GPOs that affect a

given OU or domain, use the GPMC and follow these steps:

1. Expand the console tree of the GPMC and select the OU or domain for which you want

to see the GPOs.

2. In the details pane, select the Group Policy Inheritance tab, as shown in Figure 6-2
