TITLE   :XADM: Hiding Address Book Views During Address Book View Storms
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 kbExchange550preSP4fix kbExchange550sp4Fix

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

If you create an Address Book view with multilevel containers, the directory
service (or Dsamain process) on multiple servers may peak when the directory
service populates these changes across your Exchange Server organization; you
may experience slow connections, or there may be no connections at all to your
Exchange Server computers during these Address Book view "storms."

CAUSE
=====

This issue can occur because each Exchange Server computer builds the Address
Book view based on Grouped by Attributes (GBA) that are replicated between sites
and servers. If the Address Book views are poorly designed or frequently
changed, the directory may use a large amount of the server's CPU to regenerate
these views.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.

STATUS

version 5.5. This problem was first corrected in Exchange Server 5.5 Service
Pack 4.
