Driving home and rethinking the question I realized you were not talking about A VALUE from an attribute but about the UPPER VALUE. Although it is not the actual value of the attribute I still think it will not cause a full sync because the partial attribute set is not changed #JORGE#

The samaccountname or the DN is in the PAS. So if you rename the samaccountname or DN of some object or create a sec. princ. That would cause a full sync of the GCs? In my opinion no A full (W2K) sync would be caused if you uncheck or check the box for some attribute called "Replicate this attribute to the Global Catalog". With this box you change which attributes are in the PAS. #JORGE# -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: maandag 13 juni 2005 16:50 To: [email protected] Subject: RE: [ActiveDir] Affect of a schema update on W2K SP4 AD Deji, The attribute is used by the Aelita Exchange migration product. 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/4 1641 / 41641.html Cheers #JORGE# ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: maandag 13 juni 2005 14:39 To: [email protected] 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.
