Hi, this issue was caused by the Performance Counter Library values failure, which mean some counters may be missing or do not contain counter data. The base set of performance counter libraries may become corrupted and may need to be rebuilt. Additionally, you may need to rebuild any custom (.NET Framework application created) counters or any extensible counters.

You have two options for this error:

1. Ignore this issue if you are not monitoring the ADDS. This error can be ignored only you are not monitoring the ADDS service.
2. Fix this issue by this KB article: http://support.microsoft.com/kb/300956. Before you do this, please make sure you have a latest full backup of your server, in order to prevent any potential issue of the troubleshooting steps.

Thank you!
