The following code executes on two Windows 2000 machines, but fails on a Windows XP Pro machine:

****************************************************
xxx=createobject('faxserver.faxserver')
lcNetInfo = SYS(0)
lcMachine ='\\'+alltrim( Left( lcNetInfo, AT('#', lcNetInfo )-1 ) )
xxx.connect( lcMachine )

* Create a fax document
FD = xxx.createdocument("filename") && <- FAILS HERE
fd.faxnumber = '3816405'
fd.displayname = 'VFP Fax Message'
fd.filename = fullpath("C:\junk.txt")
fd.sendcoverpage = .f.

* Send it Off!
fd.Send
*****************************************************

The error message is:

OLE error code 0x80070006: The handle is invalid

I can send a FAX from the Windows XP Pro machine by selecting the FAX option after opening the C:\junk.txt document in NotePad and selecting Print from the File menu. I have confirmed that the "Fax Services" Component has been loaded on the XP Pro machine. I am logged on to the machine as an Administrator. Are there some other DLLs that I have to register? Is there some security default setting that is different in Windows XP Pro that I have to turn off?

Beats the stuffing out of me. Any suggestions would be most appreciated.

Thanks
