Hi darren,
We have no explicit allows for administrators on lower level ou's, only
full control in the root which is inherited down.
So i presume when i explicitly "DENY" gplink, gpcreate in the root for
administrators as well (inherited), that the inherited "deny" will
override the standard inherited "allow " on each lower level ou ?
or is there still a conflict between two inherited rights?
Thanks for your great expertise by the way , and best wishes for 2007
;-)

Well, this can get complicated, esp. if you try to manage this at the
domain-level. And, for example, if you set denies at the domain level
that inherit down, then explicit allows set at the OU level will
override these.
What I would suggest, as painful as it sounds, is to set explicit gpLink
and gpOptions denies on the domain Administrators group on each OU that
you want to prevent them linking to.

Hi darren, Colin,
I have actually kinda the same problem myself but it's not on the
default permissions of the gpo.
We are having problems here because security has populated the domain
local "administrators" group with a lot of level 2 helpdesk memebers.
This gives them access on all servers as administrator (their job)
However they now can also link/create and unlink the existing gpo's in
AD
this is set on the root of the AD for administrators "full control" but
when i want to give a deny access on the specific "gpolinking" right he
wants to split out the entire full control into seperate permissions.
If we do that other functions of AD don't work correctly anymore.
Any way to remove linking and creation permissions for all except
"enterpise admins" ?

Colin-
The only way to do this actually is to modify the
defaultSecurityDescriptor attribute on the gpcContainer class object in
the AD schema (this is a mod to the instance of a schema in your domain,
not a change to the schema itself). It requires being familiar with
SDDL, but otherwise its pretty straightforward. You might want to check
out this KB and then let us know if you have questions:

Bart, thanks for the reply -
I've tried this, but there is no option on the Group Policy Objects
container which allows the setting of the AC (as far as I can see)..
I've dug a bit further and it looks like it might be possible by
modifying the domain level ACL (via the GPMC) - it looks as though I
might have to explicitly allow the Read gPOtion and Write gPOtion
properties via the advanced tab. This seems a wee bit detailed - does
anyone know if there is a less detailed way of doing this?

Hi colin,
I beleive you set the default editign permissions on
Group policy objects container (ou) in GPMC
Tab Delegation.
You have to do this for each domain. if this doesn't work you should use
an overall AD delegation object higher in the root.

Subject: [gptalk] Pre-defining default ACL on newly created GPOs
Hi,
Does anyone know if it is possible to set the default ACL which is
applied to newly created GPOs. Ideally, I'd like to be able to specify
a "GPO Modifier" group with "modify" access to each GPO as it is
created, automatically.
TIA
Colin
