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
