UPDATE 4/19/2010

The Exchange 2000 security update, 976703, contained an identifier in the metadata that was not unique enough for a WSUS API call used by SBS 2003 to differentiate 976703 from the Exchange 2003 security update, 976702.  This resulted in the error in the SBS 2003 console and the Server Status Report.

The Exchange 2000 security update, 976703, has since been expired and simultaneously re-released with modified metadata. The issue with the SBS 2003 Console and the Server Status Report will resolve itself after the next WSUS Sync.  If you did or did not decline 976703 before, there is no need to take any further action after WSUS has synced again.  You can wait for the next sync to occur as scheduled or sync manually if you wish.  After successfully re-syncing you may need to close and re-open the SBS console for the error to disappear.


After synchronizing updates released on Tuesday, April 13, 2010, the Update Services node in the SBS 2003 Console returns an error: The element already exists in the collection. Parameter name: value.
