Microsoft.Crm.Sandbox.WorkerProcess.exe Not Running

Posted on by


I have an issue with my server where the Sandbox Plugins are not working (The plug-in execution failed because no Sandbox Hosts are currently available. Please check that you have a Sandbox server configured and that it is running.), I have performed the below checks and all is ok:

Microsoft Dynamics CRM Sandbox Processing Service

    • Domain Users membership.
    • That account must be granted the Logon as service permission in the Local Security Policy.
    • Folder read and write permission on the Trace, by default located under \Program Files\Microsoft Dynamics CRM\Trace, and user account %AppData% folders on the local computer.
    • Read permission to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM subkey in the Windows registry.
    • The service account may need an SPN for the URL used to access the website that is associated with it. To set the SPN for the Sandbox Processing Service account, run the following command at a command prompt on the computer where the service is running.

      SETSPN –a MSCRMSandboxService/<ComputerName> <service account>

I have also checked the IIS bindings and the TCP port 808 is configured for net.tcp.

The Sandbox Service is running but I can see that the Microsoft.Crm.Sandbox.WorkerProcess.exe process is not running, only the Microsoft.Crm.Sandbox.HostService.exe is, there are no errors logged in the EventViewer. Has anyone experienced this issue and resolved using steps other the above ones?

Thank You.

    Hi Anne,
    I am facing the same issue but I do have event logs and it says sandbox worker Process has stopped working.
    Did you resolve this issue ?
