Error: 'FaxMaker could not initialize line - device error 34'

Author: Luis Fernandes Updated

Overview

FaxMaker Monitor displays the following error:

FaxMaker could not initialize line - device error 34.

Environment

  • GFI FaxMaker.
  • All Supported Environments.

Root Cause

This issue is usually caused when changing from one ISDN Card to another (e.g., from AVM to Diva). CAPIs from different manufacturers cannot co-exist on the same system.

Process

  1. Open the command prompt and execute the following commands: 
    • set devmgr_show_details=1
    • set devmgr_show_nonpresent_devices=1
    • start c:\windows\system32\devmgmt.msc
  2. In Device Manager, click View and enable Show hidden devices.
  3. Remove all references to non-existent ISDN devices.
  4. Uninstall the all CAPI/LANCAPI drivers from non-existent devices from the control panel.

Note: In Windows Server 2008, uninstall the drivers from the Device Manager and choose to delete drivers.

Confirmation

The FaxMaker Monitor modifies the ISDN Card to another successfully.
