I am running a Windows Server 2003 machine with fax services enabled and a US Robotics 56.6k modem. We can receive faxes just fine, however sending faxes there will randomly be a problem in that the recipient will only receive the first page of the fax and not the rest. Restarting the fax service on the machine seems to give it a jump that will temporarily fix the problem but it always comes back. There is no timetable, I will just randomly get a call from a recipient telling me they did not receive the full fax. However, the person sending the fax will get a "fax completed successfully" message stating that it sent all pages it was supposed to.
I have taken to restarting the fax service every morning but the problem will still pop up during the day. If I do not restart the fax service at least once per day, the fax server itself will seem to slow down immensely to the point where nobody will be able to fax.
Can someone point me in the right direction to find out where the problems can lie for this? I would like to get to a point where I don't have to restart the fax service every day and that I can be sure that we fully send the fax.
