Hi tony :-)
 
I would love to complete my "formation" with your article but your link you mailed me seems to be dead :(

Hi Yann

The following article provides a reasonable explanation of the role
of the Infrastructure Master:

Ok thanks for the good links :-))
 
I must apologize (again ;-), but i missed something...
 
Just for my comprehension:
I have 2 domains a and b. I add usera in groupa on DCa in domaina. DCa will create a phantom object wich is the reference of userb. right ?
No, if i delete or modify userb on domainb, the phantom must be updated in my groupa on my DCa. So it's the job of the IM on domaina to compares updated information on GCa. IM will then updated the phantom on DCa and the world goes on :-)
 
But there is one thing i didn't understand yet..... sorry :-( .... If DCa is IM+GC, then the IM can not compares and update information about the phantom because it has the latest information, so DCa will then update userb in groupa.. right ? and this change will be replicate to all DCs and GCs of the forest ? So what's wrong for placing IM on DC which is GC ?
 
Regards,
 
Yann

Hi,

For more info on the infrastructure master see "Phantoms, Tombstones and the
Infrastructure Master" (http://support.microsoft.com/?id=248047)

In both W2K and W2K3 AD.. the following rules apply:
* if you have only one domain -> make all DCs also GCs  as there is no
additional overhead
* if you have more than one domain in the forest -> for each domain in the
forest do not place the infrastructure master on a GC if you have at least
another DC in that same domain that is not a GC also!

In all cases: if all DCs = GCs there is no issue concerning the
infrastructure master.

In W2K, replication (for DCs/ for GCs) was/is of more importance because
when a group membership changed the complete members attribute got
replicated. This could be a pain, especially for universal groups

In W2K3, replication (for DCs/ for GCs) is of less importance because as
soon as you get to forest functional level windows 2003 you get linked value
replication which simply means that only the new member replicates... so
less impact! LVR also applies to other multi-valued attributes
Cheers

Hello :-)

Just a question concernng the placement of the global catalog (GC) and
the Infrastructure Master (IM) on a DC.
Microsoft said not to place the IM on a DC that is already a GC...

Why? and should it be true for an  AD 2003 forest with only one domain ?

Regards,

Yann
