Environment

  • All versions of Orion products
  • All Solarwinds Products using WMI / RPC as polling Method. 
  • Windows Server 2008
  • Windows Server 2012
  • Windows Server 2016

Cause

Event 10028 DCOM error occurs when the WMI request failed to communicate with a remote node due to Invalid Credentials or an Invalid WMI Namespace on the Target Device. As a result an event is being logged automatically on your Application Server's Event Logs.

Steps

1. Navigate to the directory from the Orion Server to verify nodes experiencing WMI challenge request (C:\ProgramData\Solarwinds\Collector\Logs)
 

2. Look for the CollectorService.log and manually search the nodes in question using the keyword CIMV2.
 

3. To Verify the Error is genuine you can perform a Wbemtest to verify if the credentials set are valid.

    a. Type wbemtest in the run dialog box.

    b. Under Namespace change root\default to root\CIMV2 then click Connect.

    c. If a second dialog box appears, repeat step a.

    d. Click Enum Classes, select Recursive, and then click OK.

You should see a display of all the CIM objects

 

3. You can also double check stored credentials in Orion to check validity by going through the following steps:

   a. Go to Orion Web Console > Settings > Manage Windows Credentials.

 

4. Another Location for Credentials if you have SAM installed:

   a. Go to Orion Web Console > Settings > Sam Settings > Credentials Library.
