How do I fix the 'No READ access to Perflib subkeys' error?

Open regedit, navigate to the Perflib key, grant Full Control to Local Service and Everyone, and then restart the Remote Registry service.

Troubleshooting No READ Access to Perflib Subkeys

When using the Performance Monitor (PerfMon) to track NCache performance counters, it requires specific Registry permissions on the target machine. If these permissions are not granted, i.e., if the account does not have READ permission on the Perflib subkeys, PerfMon cannot retrieve data from the target server.

Although the groups EVERYONE and LOCAL SERVICE normally contain READ permission by default, to resolve persistent connectivity and permission issues in a secured distributed environment, Full Control is normally necessary for the Perflib key.

Workaround

You can enable permissions on the CurrentVersion/Perflib key through the following method:

On the machine to be monitored, start regedit.
Right-click Perflib and go to Permissions.
Give full control to Local Service and Everyone users. You may have to add these users if they are not already on the list.
Go to Control Panel -> Services and restart the Remote Registry service.

You can now remotely monitor the machine.
