About the issue for the latest MP update(6.0.6000.3): “Failed to read %PROCESSOR_ARCHITECTURE environment variable from Win32_Environment WMI class.”

  • Artikel

Update: Microsoft has published a Windows hotfix to resolve this issue~

Please refer the link https://support.microsoft.com/kb/2692929 for more details: "0x80041001" error when the Win32_Environment WMI class is
queried by multiple requestors in Windows 7 or in Windows Server 2008 R2

Issue Discription:

Recently, some of customers reported that they imported the new SCCM Monitoring Pack and encountered several script errors with the error message “Failed to read %PROCESSOR_ARCHITECTURE environment variable from Win32_Environment WMI class”. Peoples on the System Center Central forum(https://www.systemcentercentral.com/Forums/tabid/60/indexId/89622/vsdCurPage/1/Default.aspx?tag=Forums+Operations_Manager) also had long discussion about this but still no workaround to resolve it.

 

Repro: <Executing multiple scheduled task(~4) to execute following script>

Environment: Windows Server 2008 R2

On Error Resume Next

Dim sCimv2namespace, sProcArchQuery, oProcArchObjectSet, oProcArchObject, sProcArch

sCimv2namespace = "winmgmts:\\.\root\cimv2"

sProcArchQuery = "Select * From Win32_Environment Where Name = ""Processor_Architecture"""

Set oProcArchObjectSet = WMIExecQuery (sCimv2namespace, sProcArchQuery)

Set oProcArchObject = oProcArchObjectSet.Item("Win32_Environment.Name=""PROCESSOR_ARCHITECTURE"",UserName=""<SYSTEM>""")

sProcArch = oProcArchObject.VariableValue

On Error GoTo 0

Select Case sProcArch

  Case "AMD64"

    REG_PATH_SMS = "SOFTWARE\Wow6432Node\Microsoft\SMS"

  Case "x86"

    REG_PATH_SMS = "SOFTWARE\Microsoft\SMS"

  Case Else

     ScriptError "read %PROCESSOR_ARCHITECTURE environment variable from Win32_Environment WMI class."

End Select

 

Investigation:

Actually, this error is caused by a Windows WMI bug, when there are multiple scheduled tasks to executing the script and it will fail after some times with 0x80041001 /WBEM_E_FAILED.

 

Workaround:

Option#1:

Modify the script to check the registry instead of WMI.

Sample:  Modify the System Center Operations Manager 2007\Health Service State\Management
Pack\Microsoft.SystemCenter.ConfigurationManager.2007.{GUID}{GUID}.xml

-------------------------------- Disable/remove all of the WMI check script in the xml----------------------------

On Error Resume Next

Dim sCimv2namespace, sProcArchQuery, oProcArchObjectSet, oProcArchObject, sProcArch

sCimv2namespace = "winmgmts:\\.\root\cimv2"

sProcArchQuery = "Select * From Win32_Environment Where Name = ""Processor_Architecture"""

....

....

ScriptError "read %PROCESSOR_ARCHITECTURE environment variable from Win32_Environment WMI class."

End Select

-------------------------------- Use following registry check script instead ----------------------------

Please note, the Sub Main of the script for ConfigMgr 2007 Monitor SMS Executive Crash Dumps would set the REG_KEY_IDENTIFICATION(not REG_PATH_SMS) after the processor architecture check.

If (CheckWow64RegistryKeyExists() = True) Then

  REG_PATH_SMS = "SOFTWARE\Wow6432Node\Microsoft\SMS"  ‘ or REG_KEY_IDENTIFICATION = REG_KEY_WOW64_IDENTIFICATION

Else

  REG_PATH_SMS = "SOFTWARE\Microsoft\SMS"  ‘ or REG_KEY_IDENTIFICATION = REG_KEY_WOW64_IDENTIFICATION

End If

------------------------------------------------------------------------------------------------------------------------------

 

Option#2:

Add code to retry the WMI Query when the query failed for the first time.

Sample: Modify
the System Center Operations Manager 2007\Health Service State\Management
Pack\Microsoft.SystemCenter.ConfigurationManager.2007.{GUID}{GUID}.xml

-------------------------------- Disable/remove all of the WMI check script in the xml----------------------------

On Error Resume Next

Dim sCimv2namespace, sProcArchQuery, oProcArchObjectSet, oProcArchObject, sProcArch

sCimv2namespace = "winmgmts:\\.\root\cimv2"

sProcArchQuery = "Select * From Win32_Environment Where Name = ""Processor_Architecture"""

....

....

ScriptError "read %PROCESSOR_ARCHITECTURE environment variable from Win32_Environment WMI class."

End Select

-------------------------------- Use following script
instead(would try to query the WMI 5 times with 5 seconds period) ----------------------------

Please note, the Sub Main of the script for ConfigMgr 2007 Monitor SMS Executive Crash Dumps would set the REG_KEY_IDENTIFICATION (not REG_PATH_SMS) after the processor architecture check.

 

Dim sCimv2namespace, sProcArchQuery, oProcArchObjectSet, oProcArchObject, sProcArch, StartTimeA, EndTimeB, TimeOutC, RetryResult, RetryCount, RetryErrMessage

‘if retry to get the value successfully, then it would not report the pervious error.

If RetryResult = false Then

    ah, maybe i should've specified that im using Notepad ++ to view the file. I just deleted the part that prompts the WMI and added the: If (CheckWow64RegistryKeyExists() = True) Then  REG_PATH_SMS = "SOFTWAREWow6432NodeMicrosoftSMS"  ‘ or REG_KEY_IDENTIFICATION = REG_KEY_WOW64_IDENTIFICATION Else  REG_PATH_SMS = "SOFTWAREMicrosoftSMS"  ‘ or REG_KEY_IDENTIFICATION = REG_KEY_WOW64_IDENTIFICATION End If in the same place.
