I have a situation where accessing perfmon counters remotely does not
display the same list of Performance Objects remotely as it does when doing
it from the host of SQL Server.

From the host of SQL Server if I run perfmon.exe I will see performance
objects for all instances of SQL Server running. I.E. all entries for
default instance "SQLServer:....", all entries for non default instance like
"MSSQL$.....".

But If I run perfmon from a remote machine I see the counters for default
instance "SQLServer:..." and some of the non default instance but not all.

If I reboot that SQL Server host, all will then be seen either locally in
the host or remotely.

What is the reason for that?

Thanks,
