Darren, thanks for the very informative post reply.

you seem only to confirm my views of what should be a relatively simple task
is not so - although happy to see this complexity reduced with GPMC does not
nothing to dispel my opinion that Microsoft seem incapable of delivering
finished products !

Thanks again

GT

Graham-
You're absolutely rigth about the dependencies between the AD and SYSVOL
portions of a GPO. As you probably have noticed, the AD portion is
stored in the Domain NC under SYSTEM\POLICIES\<GUID OF GPO> and the
SYSVOL part is in SYSVOL\POLICIES\<GUID OF GPO>. The AD portion,
formerly called the Group Policy Container (GPC) (until MS released the
GPMC and decided they didn't like any of the old names for stuff (!)),
contains attributes that reference the SYSVOL path, the version of the
GPO and some other stuff. If for example, you have used software
installation policy to deploy applications via GPO, then the GPC
contains a set of AD object known as the Class Store, which contains
packageRegistration objects for each app deployed. These objects
reference application advertisement scripts (.aas) file stored in the
SYSVOL portion of the GPO (aka the Group Policy Container or GPT).

In terms of disaster recovery of an individual GPO, you're correct that
authoritative restore isn't very flexible. Your steps below seem
reasonable although I haven't used that mechanism to restore a single
GPO before. Frankly, I think you're better off using Microsoft's free
GPMC tool to do backup/restore of individual GPOs. Its easy to use,
scriptable and restores individual GPOs with their original GUID intact.
This is a lot more flexible than authoritative restore or any other
mechanism that has to try and extract portions of a single GPO from
backups of system state.

Darren

Subject: [ActiveDir] authoritative GPO restore


was hoping to get a bit more detail on the procedure of restore of a GPO
and specifically the inter-dependencies of the sysvol folder data and AD
data

it would seem say in the scenario of an inadevertantly modified /
deleted GPO (and which has been replicated throughout the domain) that
it is not simply a matter of restore of the sysvol data, and that indeed
it is required to go through a sequence along the lines of;

boot into DS restore mode;
restore system state to its original location
restore system state to alternative location

authoritatively restore the entire database (didn't understand this - i
would have thought at most the object with the GUID of the GPO using
restore subtree ?)

restart the DC in normal mode and wait for the sysvol to mount

then a copy of what looks to be like the folder of sysvol / policies
with the GUID of the GPO from the alternative location

have derived the above from the various papers on disaster recovery et
al.

hoping people can put any of the above right, especially with notes on
the various interdependencies of the directory objects / file system
contents relating to GPO
