描述：
Source”Perflib”:服务”PerfDisk”在Dll”c:\winnt\system32\perfdisk.dll”中的打开过程用的时间比确定的等待时间要长.
解释：
完整的日志大概是：
Event Type: Error
Event Source: Perflib
Event Category: None
Event ID: 2002
User: N/A
Description:
The open procedure for service "PerfDisk" in DLL "C:\WINNT\System32\perfdisk.dll" has taken longer than the established wait time to complete. There may be a problem with this extensible counter or the service it is collecting data from or the system may have been very busy when this call was attempted.
至于微软,它的《INFO: Events for Performance Monitor Extensions (Q226494)》文章中给出这种EventID2002的解释：
Event ID: 2002
Detail Text: The open procedure for service (service name) in DLL (DLL name) has taken longer than the established wait time to complete. The wait time in milliseconds is shown in the data.
Interpretation: See the comments earlier regarding the Open Timeout registry value.
你可以在注册表的
HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\Windows NT
\CurrentVersion
\Perflib
中找一下有没有这个键值OpenProcedureWaitTime
If OpenProcedureWaitTime value is present, perflib sets up a timeout procedure internally. If the Open function of a performance monitor extension DLL does not return within the time specified, in milliseconds, in this registry value an event (2002) is posted to the Event Log. However, it only controls the reporting of the fact, it doesn't control the behavior. For example, if an Open function "hangs" then the performance monitor process will "hang" regardless of the presence of this registry value.
If the OpenProcedureWaitTime registry value is not present, the default timeout value is 10,000 (milliseconds).
解决办法：
我觉得这个错误可能和硬盘读取速度慢或者其他应用频繁读取硬盘有关系。可以调整一下超时的时间值。
