SYMPTOMS
After you upgrade Microsoft Systems Management Server (SMS) 2003 sites to SMS 2003 Service Pack 1 (SP1), performance may decrease significantly.



CAUSE
This behavior is caused by increased Discovery Data Record (DDR) processing during client authentication.

SMS 2003 SP1 lets the Discovery Data Manager reject a single DDR during client authentication without having to reject a complete batch of DDRs. The DDRs for each client are uploaded individually instead of being merged. (DDRs were merged in the original release of SMS 2003.)

If the intervals for the various discovery methods and for the collection updates have been modified to occur more frequently, the resulting increase in discovery data may affect server performance. On the site server, the increase in discovery data may also cause a backlog of .ddr files in the SMS\Inboxes\Ddm.box folder and a backlog of .rpl files in the SMS\Inboxes\Replmgr.box folder.



RESOLUTION
Increase the interval at which discovery methods and collection updates are run.
