A couple more things
– I have added the Controller (WFXCTL32.exe), WFXPING.exe and WFXMOD32.exe to the exceptions list in Windows firewall at both the Host and the Client workstation
– In the scenarios above (except the first, my mistake), I have had exactly the same version of WinFax running on both the host and client workstation (ie. 10.03 or 10.04 but not 10.03 on host and 10.04 on client)
