Event ID 29 — WMI Service Availability

Updated: August 5, 2011

Applies To: Windows Server 2008 R2


The WMI Service (winmgmt) must be available for the WMI infrastructure to operate properly.

Event Details

Product: Windows Operating System
ID: 29
Source: Microsoft-Windows-WMI
Version: 6.1
Message: Failed to Initialize WMI Core or Provider SubSystem or Event SubSystem with error number %1 . This could be due to a badly installed version of WMI, WMI repository upgrade failure, insufficient disk space or insufficient memory.


Run the WMI Diagnosis Utility (WMIDiag)

The WMIDiag tool is a script that automates various troubleshooting steps that you can use to determine whether WMI is working correctly. It provides a comprehensive report about the state of the WMI infrastructure.

Download WMIDiag. The download is a self-extracting executable. Run the executable and, when prompted, specify a folder into which to extract the files. The result should be a folder named wmidiag with three files in it: WMIDiag.doc, WMIDiag.vbs, and WMIDiag.xls.

To run the WMIDiag tool:

  1. Open a command prompt window.
  2. Navigate to the wmidiag folder that was created when you ran Wmidiag.exe.
  3. Type cscript wmidiag.vbs.

Review the report created by WMIDiag and follow the suggested problem resolution steps.


Restart the WMIDiag tool. If the problem is resolved, the tool should display the message, "SUCCESS: WMIDiag determined that WMI works CORRECTLY". If it does not report success, then it will describe the problems found and suggest steps to resolve them.
