I've search high and low for any useful information on this service and find very little documentation. The shared fax service is simple to install and create a shared fax "printer" in windows 2003. From my XP workstations I can connect to the shared printer and the local XP fax service detects the shared fax fine. However for some reason when I create a new fax and go through the wizard, it completes all the way through but nothing hits the fax queue. Only when I am logged into the workstation as a domain admin does it send correctly. I have checked permissions on the printer, the folders, the registry, etc... All is good. I've ruled out group policy. It works absolutely perfect for domain admins only, local admins or regular domain users faxes still disappear into thin air. Arghhh! There are no errors, no events generated just missing faxes... Any feedback is greatly appreciated.
