I have created a windows service to handle my the fax queue in my application.
1) By use of a timer, the service will query the database for any new faxes to be sent
2) A call to SSRS creates the fax and saves it locally as a TIFF file.
3) Then with the use of faxcomexlib, I open a connection to the fax server, attach the TIFF and send.

Code:
Dim objFaxDocument As New FAXCOMEXLib.FaxDocument
Public WithEvents objFaxServer As New FAXCOMEXLib.FaxServer

jobID = objFaxDocument.ConnectedSubmit(objFaxServer)
Everything seems to work fine until it does the ConnectedSubmit, when it throws the following error:

Operation failed. System.Runtime.InteropServices.COMException (0x80070709): Operation failed.
at FAXCOMEXLib.FaxDocumentClass.ConnectedSubmit(FaxServer pFaxServer)

I looked up that error code and it is "the printer name is invalid". I have searched the internet for days looking for this error while faxing to no avail. There is no method for setting the printer name with the faxcomexlib... nor should it be necessary. I have run the same code from a web application without issue, but need to get it working as a windows service.

Hi,

Similar operation failed errors received when dealing with FAXCOMEXLib are documented on the InterFax site. This page includes common FAXCOMEXLib problems and solutions collected from major tech forums and links to the discussions as well.
