WinFax 10.03 on Windows Server 2003

I have a client with a Windows Server 2003 server. I am trying to get WinFax to run on it. Faxing from the WinFax app works fine, but I can’t fax using the fax printer drivers. I had to change a group policy to allow kernel-mode drivers to even get the fax printer to install. When I try to use the photo-quality fax printer, I get a blue-screen. When I try to use the regular one it starts to work, but eventually locks up. The version on the WinFax disc says 10.0, but the About dialog says 10.03. Symantec KB only lists 10.0 and 10.02. What gives with that?
