Hi All,


I recently started a new company and am in the process of tidying up their Group Policy and Active Directory settings.


They have two computers in an OU with loads of Group Policies attached to it.  Most of the settings are in the User Configuration section.


Do these apply to computers?


Thanks
D

No they won't apply to computers but check to see if loopback processing is enabled.  If it is enabled then those policies will apply

Nope - User configuration settings only apply to Users in the OU that policy is applied to.  2 computers with User Configs will not be applied via GPO because they are not Users.

how mkline71 say:
with loopback-policy enabled the user-part of a gpo at a computer-container are applied if a user logon to a computer from this OU.

this user policy can completely replace the user-GPO from his OU or can extend the user-settings.

He said that Most of the Settings are User settings and he asks if the GPOs will apply to the computers.  The answer is the settings for user will only apply to the user and anything that has computer settings will apply to the computers.  The easiest way to see which GPOs applies to the computer is to run either gpresult /SCOPE COMPUTER /V.  If you want to run this command in a Win Vista/7/2008, you have to run the command prompt as administrator.  Another way is running rsop.msc (But in Vista and Windows 7 you do not see all the settings configured)

I agree with dkotte, but will elaborate a bit to explain why it's that way...

The SHORT answer to the original question is NO, because as some people have stated, USER policies only apply to USERS, and COMPUTER policies only apply to COMPUTERS.  UNLESS

To understand the loopback processing stuff, you have to have a little more background:

Computer policies for a particular computer are taken from the OU that the COMPUTER is in (and inherited from above)
User policies are applied from the OU that the USER is in..

Computer policies in the OU of the user, or vice versa, would have NO AFFECT.

So, imagine this scenario - You've used a GPO to assign Microsoft Office 2010 to be installed when the USERS log on.  This works great, until one day you log on to your Exchange server, and Office gets installed on it...
To avoid situations like that, turning on loopback processing can tell the system basically to cause any user that logs onto that computer to get it's user GPOs from the same OU that the computer is in, either INSTEAD OF, or IN ADDITION TO the GPOs from the actual user's OU.

The loopback processing itself is a computer setting, so it can be set in a computer GPO for the OU.  It can be found under Policies / Administrative Templates / System / Group Policy, as shown in this picture:
Loopback Processing
just set it to "Enabled", then choose the "Mode" of "replace" or "merge"

Hope that helped, with all the info in one place.
