FAXCOMEXLib Fatal Error in Remote Fax Queue RRS feed

  • Question

  • I have written a C# console application that uses FAXCOMEXLib.

    The application reads in a text file and submits it to the fax queue.

    (1) The fax queue is running on Windows 2003 SBS  (ServicePack2) (and is working fine), by manually sending faxes to the Fax Server using the traditional File->Print from a application.

    (2) I've developed a application using Visual Studio 2013 Express C# console app.

    (3) Running the console app on my Windows 8 Enterprise development machine works fine, and submits the document to the fax server on the Windows 2003 server SBS (ServicePack2), and sends successfully

    (4) If I deploy the console app to a Windows 2008 server  (ServicePack2) the following happens;

    • I had to install the fax service on the local machine, even though the fax is being sent via another fax server, otherwise I get the error "Retrieving the COM class factory for component with CLSID {CDA8ACB0-8CF5-4F6C-9BA2-5931D40C8CAE} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).|"

    • The app runs fine, once the fax service is installed

    • The fax is submitted to the fax queue successfully

    • I can see the fax status in the queue as Pending, followed by Dialing and then Transmitting.

    • However after a while, I get a error Fatal error, and the fax doesn't go.  The fax number is fine, and can receive a fax using the traditional File-Print (send to fax method).

  • Hi NeilDT,

    I think there was something wrong with the configuration of the Windows server 2008. Please post thread on Windows server forum for more information about configuration.
