Title: 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
