Windows Fax Routing Not Working

I used Windows Fax on my terminal server running Win 2003 Server. It worked
OK for years and I would route the incoming faxes to a folder on the network.
Recently there were lines missing on each received fax so I tried to install
a new fax program that would allow me to make flow control changes, unlike
the Windows fax program/service. The new program didn’t work at all so I
reinstalled Windows fax except now I cannot route the received faxes to the
old folder that used to receive them or any other folder for that matter,
regardless of their permissions. When I try to set the routing up in the
configuration wizard or directly in the device properties, I get the
following error message: The FaxService cannot access the folder specified.
This didn’t happen in the past and I’m pulling my hair out trying to figure
out how to correct it. I have this problem regardless of whether I’m logged
on as the network administrator or the local computer administrator and
whether I route the fax to a network folder or local computer folder. What
object do I set the permissions so that the routing will work.
