- In the Group Policy Microsoft Management Console (MMC), click Computer Configuration.
- Locate Administrative Templates, click System, click Group Policy, and then enable the Loopback Policy option.
Note Loopback is supported only in an Active Directory environment. Both the computer account and the user account must be in Active Directory. If a Microsoft Windows NT 4.0 based domain controller manages either account, the loopback does not function. The client computer must be a running one of the following operating systems:
- Windows XP Professional
- Windows 2000 Professional
- Windows 2000 Server
- Windows 2000 Advanced Server
- Windows Server 2003
Note You cannot filter the user settings that are applied by denying or removing the AGP and Read rights from the computer object specified for the loopback policy.
Normal user Group Policy processing specifies that computers located in their organizational unit have the GPOs applied in order during computer startup. Users in their organizational unit have GPOs applied in order during logon, regardless of which computer they log on to.
In some cases, this processing order may not be appropriate. For example, when you do not want applications that have been assigned or published to the users in their organizational unit to be installed when the user is logged on to a computer in a specific organizational unit. With the Group Policy loopback support feature, you can specify two other ways to retrieve the list of GPOs for any user of the computers in this specific organizational unit:
- Merge Mode
In this mode, when the user logs on, the user's list of GPOs is typically gathered by using the GetGPOList function. The GetGPOList function is then called again by using the computer's location in Active Directory. The list of GPOs for the computer is then added to the end of the GPOs for the user. This causes the computer's GPOs to have higher precedence than the user's GPOs. In this example, the list of GPOs for the computer is added to the user's list.
- Replace Mode
In this mode, the user's list of GPOs is not gathered. Only the list of GPOs based on the computer object is used.
