SBS 2003-cannot reinstall fax service

I have been unable to reinstall the fax service on my sbs 2003 server box.
I have researched it a bit and found a common thread on the internet, but
the fax service still will not install from the add\remove programs\sbs
2003 entry. It finishes with 'cannot install fax service. please try
again'
Any and all help is greatly appreciated. I imagine the logs tell the
story, but i am unable to interpret them. Thank you all
