Getting the following error:

If all needed Service Packs are installed and the error still persists, do the following:
Turn off the following data collection schedules for selected connection(s) to suppress Performance object... not available alarms:
- NBT
- LogicalDisk
- Network
Restart the diagnostic server service.
The resolution above will disable attempts to collect data from NBT performance object (which is unavailable) and suppress the mentioned alarm.
It is not a bug in Spotlight SQL Server Enterprise. There were no NBT-connections opened on the monitored machine and NBT performance object was unavailable.
When mentioned data collection schedules enabled, the Diagnostic Server attempts to access NBT performance object and as a result error occurs.
