I have two networked computers in my office running Windows XP Pro. Computer A is connected to a Brother multifunction printer/scanner/fax machine which connects to a phone jack for faxing, computer B where I work on is nowhere near a phone jack. I can send PC faxes (through my Brother multifunction machine) from computer A, but I can't send the PC faxes from computer B over the network to the multifunction fax machine which is attached to computer A. When I go into the control panel to try and share the PC fax (Windows XP sees this as a printer) it says this cannot be shared.

Is there any way I can send PC faxes from Computer B, when computer A is the only one near a phone line? I can buy a PC fax card if it will allow me to do this, I don't know if it will work.
