2008 64bit Fax Server with 32bit XP Clients

I have been trying to get this to work for months now with no luck. Server is 2008 64bit. All clients are XP sp3 32bit. Both 32bit and 64bit drivers are installed on server (32bit drivers were loaded from a vista disk prnms002.inf). When you select send fax nothing happens. When you print to fax printer from an app nothing happens but the console that pulls up shows "ready".

Please help!
