Performance counter not working in Perfmon

[Guest markeboy]

I have a simple custom performance counter that is created each time my

service starts. The category is created at install time.

 

I can connect to the service's process and see my counter incrementing

correctly. Perform shows this value as 0 regardless, however this was

working a few reinstalls ago. It did stop working after I had to reboot my

computer to fix a "this installation has been marked as deleted (or similar)"

error message.

 

I am sure I am checking the correct counter as when this in uninstalled the

counter category is removed. I can see other non custom counters correctly

in perfmon

 

I am running WIN2K3 SP2. Any issues or explanation for this behaviour?
