TITLE   :SMS: DDM Fails to Process DDR w/ Assigned Sites Set to <Unknown>
PRODUCT :Microsoft Systems Management Server
PROD/VER:winnt:2.0
OPER/SYS:
KEYWORDS:kbsms200 kbsms200bug kbsms200fix kbDiscovery

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

 - Microsoft Systems Management Server version 2.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Newly discovered computers may not show up in the Systems Management Server
Administrator Console, Collections node under any collection. The Ddm.box
directory on the Site Server may contain a large number of DDR (Discovery Data
Record) files and the Ddm.log may show the following messages:

   ~SQL Err #10007> General SQL Server error: Check messages from the SQL
   Server.
   ~SQL Msg #2627> Violation of PRIMARY KEY constraint
   'System_SMS_Assign_ARR_PK'. Cannot insert duplicate key in object
   'System_SMS_Assign_ARR'.~
   ~SQL Msg #3621> The statement has been terminated.~

CAUSE
=====

If the DDR being evaluated by the Discovery Data Manager (DDM) has an
AssignedSites property value of Unknown in it then DDM might fail to process the
DDR and stop processing the rest of the DDRs.

WORKAROUND
==========

A current workaround is to stop the DDM component through the Systems Management
Server Service Manager in the Administrator console, remove the DDR in process
at the time and then restart the DDM component.

STATUS
======

Microsoft has confirmed this to be a problem in Systems Management Server
version 2.0. This problem has been corrected in the latest U.S. service pack for
Systems Management Server version 2.0. For information on obtaining the service
