I'm having an issue with a SQL 2000 cluster.  On each node, there always
seems to be only one instance of perfmon SQL objects available at a time. 
There are 3 instances of SQL installed on the cluster, default, PROD0 and
PROD1.  On each physical node, opening perfmon to set up counters, there is
always only one set of SQL objects available.  for example, as I write this,
only the default instance counters are available (SQLServer:<objectname>) on
the active node, but on the passive node, only the MSSQL$PROD0 objects are
available. 

Any ideas?
