WMI troubleshooting

Note that remote tools in RDP sessions will not work in Remote Desktop Manager if you do not have WMI. Consult this guide on remote WMI.

In our environment, we basically run winrm quickconfig on all our machines. For those not joined to a domain, we also add them to the TrustedHosts list. For machines not joined to a domain, there is an added difficulty. If you are using the IP address instead of the host name, it definitely offers a few challenges.

A good strategy is to get remoteWMI to work, then integrate it in Remote Desktop Manager. We like to use WMIC.

Problem 1

Access denied error.

Solution

Make sure that the user account has the necessary permissions to access a computer remotely. See Securing a Remote WMI Connection (Windows).

You can also find troubleshoot tips in WMI Troubleshooting (Windows).

Problem 2

Error getting products informations.

Solution

Invalid Class WMI or WMI class not found on Windows Server 2003. On Windows Server 2003, Win32_Product is not enabled by default. You can enable it by following the steps provided in this Microsoft Forum.

Problem 3

Testing from a remote computer.

Solution

The WMIC command is used to test if you have access to the machine through WMI. You need to enter the following command: wmic /NODE:"ComputerName" bios get serialnumber

Below is an example with other credentials: wmic /NODE:"ComputerName" /user:"username" /password:"password" bios get serialnumber

Problem 4

Load from System Information does not work. Error getting Bios information.

Solution

This error can have several origins. Please validate the following:

  • Sessions must be RDP.
  • The station must be on the same domain.
  • The credentials must be in the Tools section of the session and be accurate.
  • Test the WMI requests directly from the station to see if the communication is working.
