FAX Service on SBS 2003 will not stay running.

I have a critical situation with a client:

SBS 2003 with a Brooktrout Fax card internal and USR Courier External.  External handles incoming faxes and internal handles outgoing.  Everything has been running great for approx 18 months.  Starting yesterday around 10:00 the Fax Service will not stay running.  Within 10 seconds of starting it shuts down.

I have installed all the updates including Server 2003 SP2.

Here are the relevent log entries:
