Subject: [ActiveDir] Contents of GC
Hi Everyone,
The following situation....
THE FOLLOWING ENVIRONMENT IS AN
EXAMPLE:
* 1 forest with 3
domains (W2K Native Mode)
* DOM_A is forest root
* DOM_B is a child domain of DOM_A
* DOM_C is a child domain of DOM_A
* Each domain has 5 DCs
* Each DC = GC
On
T=0 : all DCs/GCs are
in sync
T=1 : backup made of all DCs in forest (system
state)
T=2 : addition of 10000 objects to DOM_B
T=3 : all
DCs/GCs are in sync again (all GCs in DOM_A & DOM_C contain the 10000
objects from DOM_B)
T=4 : some time later
T=5 : ALL DCs in DOM_B
crash or dy or whatever (don't function anymore)
T=6 : Restore all DCs
in DOM_B from the backup made in T=1
After the restore is finished al DCs from DOM_B boot and are OK again
SITUATION:
All GCs from DOM_A & DOM_C contain
information about the 10000 objects from DOM_B. These objects reside in the GC
data but the domain data (DOM_B) does not even know of the existance of those
objects because all DCs have been restored. The GC data is newer than the domain
data.
How to deal with?
SOLUTION 1: (I know this one works, but with a
forest containing a lot of DCs/GCs I'd rather not do this)
* Demote all GCs in the forest? (wait until
all GCs are fully demoted)
*
Promote all DCs to GC again
SOLUTION 2: (I hope something like
this works)
Is it possible to
say:
* Tell all GCs to remove
the read-only naming context of DOM_B and rebuild it again (is REPADMIN able to
do this?)
SOLUTION 3:(I hope something like
this works)
Is it possible to
say:
* Tell all GCs to check
the read-only naming context of DOM_B against the DCs of DOM_B and remove all
objects from the GC data that do not exist in DOM_B
SOLUTION 4:
Something else?????
I hope someone can answer this
Thanx in advance!
Regards,
Jorge
Does somebody know how or which tool is able to check if a certain object is stored in de read-only naming context (of a certain domain) of the GC?
Environment:
* W2K3
* 3 domains
* 1 DC per domain
* Each DC = GC
* No Exchange
