Originally, this article was going to called, "WMI Best Practices." After doing a brief search, I stumbled upon Microsoft's version of this topic. (They are, after all, the creators of WMI.) Let's just say the material was...sparse.


I think helping troubleshoot a WMI node would be more beneficial to our community anyway, so let's go with that.


Troubleshooting a WMI Node.


The following conditions must be met before you can proceed troubleshooting WMI nodes:

  • The node has successfully been added via WMI.
  • WMI is working properly on the remote server.
  • The Hardware Monitoring is installed on the remote server and running.

Using Wbemtest.exe to troubleshoot WMI:

  1. Open wbemtest.exe, usually located at C:\Windows\System32\wbem\wbemtest.exe.
  2. Connect from the problematic node (either the SAM server or the additional poller server) to the remote server using wbemtest.exe.
  3. Click Connect.
  4. In the Namespace field enter:

For IBM and HP enter: \\RemoteServerIpAddress\root
For Dell enter: \\RemoteServerIpAddress\root\cimv2


   5. Enter administrator credentials.


   6.  Click Connect.

   7.  Once connected, click Query… from the main screen. The Query dialog appears.

   8Enter: select * from __Namespace


Replace Namespace with the following:

  • For HP nodes, replace Namespace with HPQ
  • For Dell node replace Namespace with Dell
  • For IBM node replace Namespace with IBMSD

  9.   If the proper Namespace is found, connect to this Namespace.

  • \\RemoteServerIpAddress\root\IBMSD for IBM.
  • \\RemoteServerIpAddress\root\HPQ for HP.
  • \\RemoteServerIpAddress\root\cimv2\Dell for Dell.


  10.  Run a Query for specific information.

         Select Manufacturer, Model, SerialNumber from CIM_Chassis

  • If the test was not successful, re-install the Hardware agent software provided by the vendor or Hardware Monitoring on the remote server with the latest release.
