Dean - thanks for the pointer. That article was the key. I went back to the lab and applied the change (change rangeupper to 4096). I then looked on an existing GC and it did not have the event 1575 in the directory services log. Given this, I think that the answer is that the update does not cause a full GC sync, which makes sense since the full sync occurred when forestprep modified the schema the first time and I am now modifying an existing object....
Thanks everybody....

It's already added and replicated (via Full GC Sync) to all GCs in the forest during the prepping (schema extension). Changing just the ms-Exch-Extension-Attribute-15 or even deleting it will NOT cause a full sync. My bad. Sorry to have to send you to the Lab.

I am having to change it because Aelita uses it to store the alternate recipients and I have a few Exc 5.5 mailboxes that blow it past the 2048 default. I am now concerned because I have conflicting answers. I have one answer from MS (and you) that says the change will kick off a full sync and I have another from somebody else at MS that matches Jorge's answer that it won't. All of the docs that I read indicate that when you update the schema by adding an attribute that is in the PAS (i.e. E2K3 forestprep) it will cause a full sync on a W2K directory. I have not found a mention of what happens when you update the definition of an existing schema attribute (which is what I need to do). This is why I asked the original question ;-) I guess that I am off to the lab... BTW - If anybody has any pointers to any definative documentation on this it would be greatly appriciated...

As a result, you will still be doing a full GC sync. I have a q, though. Why are you increasing the RangeUpper? I am just curious and asking for my own education.

The PAS is the Partial Attribute Set...in other words the set of attributes in the GC. Only if you change that set (add or remove an attribute to/from the set) will cause a full sync of the GCs if W2K. This will not occur in W2K3 as in W2K3 it only replicates the new added/removed attribute. So in W2K only when changing the SET will cause a full sync, NOT when changing the value of an attribute in the set. The change of the value will of course replicate to all GCs in the forest See also: http://www.windowsitpro.com/MicrosoftExchangeOutlook/Article/ArticleID/41641 / 41641.html Cheers #JORGE# ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: maandag 13 juni 2005 14:39 To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Affect of a schema update on W2K SP4 AD All, I am running a W2K SP4 AD and am in the process of migrating to Exc 2003. I have already applied the Exc 2003 forest prep and domain prep. I now have a need to increase the rangerupper on ms-Exch-Extension-Attribute-15 from 2048 to 4096. This attribute is a member of the partial attaibute set. The question is will the update to the rangeupper on an existing attribute cause a complete GC synch? I suspect that the answer is yes but I just want to confirm this.... Thanks in advance.... Frank This e-mail and any attachment is for authorised use by the intended recipient(s) only.
