FaxFinder FF420 File Share PDFs are 0KB

Hello. I have a Multi-Tech FaxFinder FF420 fax server. The server is configured to write the faxes over to a file share. We recently upgraded the file share server from Windows 2000 Advanced Server to Windows 2012 Standard.  Now the faxes that are written to the file share have a file size of 0KB.

I have thought of permissions issues, SMB settings and other security features but if it were a permissions issue the file shouldn't be writable in the first place.

We have a multi function Kyocera that write PDFs and TIFs to the server.  We have users (Windows 10 clients) that access file shares able to read/write.

Any ideas?

How old is this software? Fastest way, try FTP transfers instead (Win2012, install Filezilla Server).
Downgrading the Win2012 server to SMB1 is also an option, but it's less safe.

Multitech FaxFinder is a fax server appliance.  It's a piece of hardware.  It receives incoming faxes and writes them to a file share.  It's a model 420.  FTP is not the solution for real time incoming faxes.  We receive thousands of faxes every day so a fax server solution seems to be the best way to go.

While it's a piece of hardware, the question I asked ("how old is this software") still applies. Hardware doesn't work without software after all. If you don't know from when the software is, it's probably never updated since it was manufactured/you bought it.
FTP is a transfer method, just like you're currently using SMB, so saying it's not the solution for real time incoming faxes doesn't really make any sense. Obviously, the function needs to be embedded in the Fax server software already (but I think I already saw it mentioned in the manuals)

The Multitech fax server has it's own firmware/software.  The FF420 model has been around for at least 11 years.  According to the doc on the mutlitech site, our company has the FF420 current firmware for the device.  Thanks.

As the firmware is already 8 years old, you should still try to downgrade to SMB1 on the server.
Also, if that doesn't work, maybe change the configuration back to email, and find an email solution to save the files to the final location (have Outlook do it with VBA)

Thanks.  According to the Microsoft KBs and tests I've done SMB v1 is enabled as well as SMB 3.  So now after my testing I don't think SMB adjustments will resolve the problem.  There's a powershell script that can be run that checks for the presence of SMB v1.  I ran that and it came back TRUE.
