Related Articles


To detect the configuration of a computer, Octopus uses the Windows Management Instrumentation components (also called WMI) installed on the computer to be inspected.
Different errors can happen during the inspection. The table below shows the most common errors and provides clues for correcting them. 

 Note that the explanations / resolutions proposed are based on our experience with WMI - they may not be the only possible reasons for resolving the errors.

Error Message Defenition

Unknown Computer


  • Unable to resolve the computer name to an IP address.

Explanation / Resolution

  • The most probable scenario is that this computer no longer exists. If it is the case, change the Octopus status to "Retired" or remove the CI from your Active Directory, it will be detected as retired at the next import

  • There is an error in the computer name

  • There is a technical problem. As long as you are not be able to do a successful "nslookup", the problem will persist

  • A laptop that rarely connects to the domain may get this type of error.

Connection Timeout


  • The computer name is recognized ; however, it is impossible to connect to it.

Explanation / Resolution

  • The computer is turned off

  • The computer is not connected to the network

  • The computer belongs to another network/domain that is not "visible" from where the WMI detection is being done. In this case, the detection must be done on a computer that belongs to the same network

Access Denied


  • Does not have the correct rights to inspect the computer.

Explanation / Resolution

  • The network account used to do the inspection does not have the minimal required permissions for the detection. We recommend that you use an account with administrator rights on the domain.

RPC Error (RPC Error)


  • The computer refused to establish a RPC type connection.

​Explanation / Resolution

  • The computer has an active firewall. The installation of Windows XP SP2 or Windows Server 2003 automatically activates a firewall. You must deactivate the firewall or congirure is to accept RPC type connections

  • The RPC service is deactivated or does not work.

Error during process


  • WMI internal error.

Explanation / Resolution

  • The WMI installation of the inspected computer is faulty. Check the WMI installation

  • The default installation of Windows Server 2003 does not include the WMI components. You must install the components manually.

Reading Timeout


  • The inspection has exceeded the maximum time allowed.

Explanation / Resolution

  • The computer inspected could not provide its configuration in the expected time. The computer is too busy to process the request or a technical problem prevents the inspection from being completed.

Unknown error


  • An unexpected error occurred during the inspection.

Explanation / Resolution

  • A technical problem on the computer prevents the inspection from being completed.

Serial Number Mismatch


  • The name and serial number of the workstation don't correspond with the computer's history.
  • The serial number has been modified in the CI file directly and does not match the computer's history, which disables the CI updating process..

Explanation / Resolution

  • The computer name has been used on another workstation. When you replace a computer, if you want to use the same name, you must rename the old one in Octopus first.
  • Put back the original serial number which is written down in the history and right after, WMIUpdater will be able to update the fields at its next execution.
