SYMPTOMS
The Windows 2000 Application event log may be populated with several event 2002 Perfproc errors that have the following (or similar) description:

Unable to open the job object Winlogon Job 0-13f0822 for query access. The calling process may not have permission to open this Job. The status returned is data DWORD 0. For more information, see Help and Support Center at http://support.microsoft.com.



CAUSE
Perfproc.dll logs the 2002 event error when it cannot open a job object. Refer to the &quot;More Information&quot; section for additional information.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

260910 How to Obtain the Latest Windows 2000 Service Pack

Perfproc.dll was modified to call OpenJobObject using the full path in the object name space from the \BaseNamedObjects path.

The English version of this fix should have the following file attributes or later:

  Date        Time     Version       Size    File name 12-Feb-2002 04:48PM 5.0.2195.3990 28,944  Perfproc.dll



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.



MORE INFORMATION
A job object allows groups of processes to be managed as a unit. In this case, Perfproc cannot open the Winlogon job object because no user is logged on to the console and a process that is running as a service or in a terminal server session requests process performance data (which is implemented in Perfproc.dll). The open process fails on the Winlogon job object because Perfproc.dll calls OpenJobObject with the job name instead of with the full path to the job. When OpenJobObject is called with a job name instead of the full path to the job in the object name space, it looks for the job under the running processes session sub-tree which will fail if there is no user logged on to the console.
