Description
The attempt to collect network services performance data failed because the DLL did not open successfully.

1. Check that the dll %windir%\system32\perfnet.dll exists (in my case, the dll’s version was 5.0.2164.1). If it does not exist, try to copy it from a different system.
2. Check that SYSTEM has Full Access.
3. Check that the performance extension DLL is enabled. See ME248993 for details.

In my case, the error was “No Registry-Key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfNet\Performance\Open”. I created this entry as [REG_SZ] with the value “OpenNetSvcsObject” and the problem was solved.

From Exctrlst-Help: “Open Procedure - The name of the function that is found in the DLL file, which performs the initialization of the performance, functions for this service. This function must be exported by the DLL and return a successful status for the registry to collect performance data from this service. If this function is not found in the DLL or returns an error, the registry will log an error in the system’s Application Event Log”.
