Novell ZENworks 10 Configuration Management with Support Pack 3 - 10.3
Dynamic Groups do not show expected number of members
Dynamic Groups never show more than 500 entries
This is fixed in version 10.3.1 - see KB 7006265 "ZENworks Configuration Management 10.3.1 - update information and list of fixes" which can be found at https://www.novell.com/support
Results tables for Dynamic Groups were previously limited to 500 entries (this could include duplicates, so when they were removed, the final result could have fewer than 500 entries).
