We have added a W7 Pro client pc to our domain - server is SBS 2003 SP2. Shared fax is working fine for all other XP Pro PC. will not work on W7P or W7Px64. Discovered that instaed of pointing it at \\sbs_server\fax_name point it to \\sbs_server it sort of works - insofar as it now sends but just sends a blank page i.e. fax is getting added as an attachment!
