Here we go again

Try it as:
DBCC INDEXDEFRAG (Master,"dbo.spt_values",ix2_spt_values_nu_nc)

DBCC INDEXDEFRAG (AdventureWorks_regular,"cdc.ddl_history",ddl_history_clustered_idx)-- a system table in the AdventureWorks_regular DB

Your reference states
DBCC INDEXDEFRAG cannot be used to defragment the following indexes:

A disabled index.

An index with page locking set to OFF.

A spatial index.

DBCC INDEXDEFRAG is not supported for use on system tables.


It may be depreciated in the future and it may not be supported on system tables ...BUT IT WORKS NOW in both the MASTER DB and a system table in the AdventureWorks_regular data bases using SQL 2008 or SQL 2005

My testing:
Using 2005

DBCC INDEXDEFRAG (Master,"dbo.spt_values",ix2_spt_values_nu_nc)--Original system table
Pages Scanned Pages Moved Pages Removed
14 6 4
Using 2008
DBCC INDEXDEFRAG (Master,"dbo.spt_values",spt_valuesclust)--System table
Pages Scanned Pages Moved Pages Removed
18 8 3
Using 2008
DBCC INDEXDEFRAG (AdventureWorks_regular,"cdc.ddl_history",ddl_history_clustered_idx)-- a system table in AdventureWorks_regular
Pages Scanned Pages Moved Pages Removed
14 6 4

If everything seems to be going well, you have obviously overlooked something.

Neither of those are system tables, they are ordinary tables that happen to be used by the system :-)
