DXH ContextBus Service Is Not Running On the Server

  • Updated

This article covers the issue when the DXH ContextBus service will not launch on the server. A small note in the documentation indicates that TCP Port Sharing and HTTP Activation need to be enabled for proper service functioning. This is often missed and addressed here.

If the DXH service is not running on the server, subsequent calls by the product will fail. The error below may be one of many errors you would see in this event.

Message: DXH Service Will Not Start: Faulting application name: CBSvcHost.exe, version: Faulting module name: KERNELBASE.dll, version

Please review the following documentation.

Prerequisites: DXH System Requirements

Once you complete these steps, restarting the server usually resolves the issue.
