SBS 2008 Fax Problems Sending From XP.

Hello all

I am having problems getting my xp machines to send faxes from their workstations to a SBS 2008 fax. I can send and recieve faxes from the server perfectly. But when i install the fax on the xp machines and click send or print to the fax the egg timer comes on then goes off. Then nothing happens.

I have tried a few steps which is below on the link.

If anyone can help i would be very grateful as i am pulling my hair out.

Thanks Scott
