Titolo: Impossibile caricare perfproc.dll

Salve a tutti!
Ho un PC con Win 2000 SP1 ITA e NT 4.0 che mi fa impazzire: a volte si 
resetta casualmente, in altri casi si chiudono improvvisamente tutti i 
programmi. Nel tentativo di isolare le possibili cause analizzando 
l'Event Viewer (di Win2000) ho notato il seguente errore:
Origine: WinMgmt
ID evento: 37
Impossibile caricare la libreria di prestazioni perfproc.dll
Problema sconosciuto nella libreria: 0x0
E' un errore noto? Cos'è WinMgmt (lo vedo nel taskmanager)?
A cosa serve la dll in oggetto?
Può essere un problema HW. Ho già controllato l'HD IBM che le apposite 
utility, disabilitato da BIOS tutte le periferiche non necessarie e 
sostituito la RAM ma senza risultato.
La mia configurazione:
ASUS CUV 4XM Bios 1004
PIII 733EB (S.370 Fc-Pga) 133MHz
256 MB 133 MHz
IBM DTLA-307030 30.7 GB U-ATA100 7200rpm
Guillemot 3DProphet SE GeFORCE 256 16MB
CD-ROM Asus 50X
3Com 3C905B-TX
Grazie a chiunque sappia aiutarmi
Edo

Io ho un portatile IBM win 2000 e il tuo stesso problema, ma io lo
attribuivo al fatto che avevo installato e disistallato la SP1.
ora mi metti un bel dubbio, visto che effettivamente il computer è
rallentato...
non ho ancora provato ad eliminare il prob.
ciao! enrico.

ciao! enrico.
Anch'io ho lo stesso problema. Ho installato Win2000 da tre settimane,
SENZA SP1, e la libreria non si carica da una decina di giorni.
Grazie a chi sapra' dare indicazione sulla soluzione del problema.

Troubleshooting WinMgmt-Based Performance Counter Errors 
--------------------------------------------------------------------------------
The information in this article applies to:
Microsoft Windows 2000 Server 
Microsoft Windows 2000 Professional
--------------------------------------------------------------------------------
IMPORTANT: This article contains information about editing the
registry. Before you edit the registry, make sure you understand how
to restore it if a problem occurs. For information about how to do
this, view the "Restoring the Registry" Help topic in Regedit.exe or
the "Restoring a Registry Key" Help topic in Regedt32.exe.
SYMPTOMS
When you view the Application Event Viewer log on your computer, you
may see one or more of the following entries: 
Event Type: Error
Event Source: WinMgmt
Event Category: None
Event ID: 37
Description: WMI ADAP was unable to load the file name performance
library due to an unknown problem within the library: 0x0
Event Type: Error
Event Source: WinMgmt
Event Category: None
Event ID: 41
Description: ADAP was unable to process the file name performance
library due to a time violation in the collect function
Event Type: Error
Event Source: WinMgmt
Event Category: None
Event ID: 61
Description: WMI ADAP was unable to process the file name performance
library due to a time violation in the open function 
CAUSE
These events can be logged either because of a problem in the counter,
or a false positive return value in the Windows Management
Instrumentation (WMI) Performance Library Dredger. In the latter
instance, in certain situations, the dredger incorrectly determines
that a library is invalid even though the counter works correctly. 
WORKAROUND
WARNING: Using Registry Editor incorrectly can cause serious problems
that may require you to reinstall your operating system. Microsoft
cannot guarantee that problems resulting from the incorrect use of
Registry Editor can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing
Keys and Values" Help topic in Registry Editor (Regedit.exe) or the
"Add and Delete Information in the Registry" and "Edit Registry Data"
Help topics in Regedt32.exe. Note that you should back up the registry
before you edit it. If you are running Windows NT or Windows 2000, you
should also update your Emergency Repair Disk (ERD).
First, try once more to dredge the system's performance libraries
using the following commands: 
WINMGMT /CLEARADAP 
This command clears all Web-Based Enterprise Management (WBEM) related
values from the service's performance registry key. 
WINMGMT /RESYNCPERF "winmgmt service PID" 
This command registers the the system's performance libraries with the
WMI.
The WMI service PID information can be found in the Process tab of
Windows Task Manager.
The performance registry keys of the involved services are:
WbemAdapFileSize
WbemAdapFileTime
WbemAdapStatus
Note: For more information about the command line options available
with WMI, type winmgmt/? at a command prompt. 
Another possible reason for the above events may be that the counters
are slow to respond due to other activities during startup. It is
possible to tune this timeout by adding the value Collect Timeout
REG_DWORD 10000 to the appropriate registry location: 
HKey_Local_Machine\System\CurrentControlSet\Services\[counterfile]\Performance
If events continue to be logged after making the above changes, change
the WbemAdapStatus value manually to REG_DWORD 0 under the service's
performance registry key and increase the ADAPPerflbTimeout value to
REG_DWORD 180 under the following registry key: 
HKLM\Software\Microsoft\Wbem\CIMOM 
Note: All registry changes have to be entered as decimal values. 
In addition, it is possible to disable performance counters for a
specific service with the Exctrlst.exe utility from the Windows 2000
Resource Kit.
This utility disables the specific counter by adding a registry key
similar to the example below. These registry entries can be added
under the specific counter entry manually if Exctrlst.exe is not
available or desirable. 
HKLM\System\CurrentControlSet\Services\Spooler\Performance
Value Name: Disable Performance
Value Type: REG_DWORD Value Data: 1 
MORE INFORMATION
The AutoDiscovery/AutoPurge (ADAP) process is responsible for
collecting and maintaining performance counter objects in WMI that are
registered on the computer.
The ADAP process starts when the WinMgmt service is started or when
performance libraries, which contain the performance counters, are
installed or uninstalled using the lodctr/unlodctr utilities.
Although the above entries are logged, the counters are still
available.

Grazie,
l'esecuzione di questi 2 comandi ha risolto il mio problema.
