SYMPTOMS
After you install a third-party fax program to use with Microsoft Exchange in Microsoft Small Business Server (SBS) 2003, faxes from clients are not sent, and the fax software does not report an error.



CAUSE
This problem occurs because the Microsoft Exchange MTA Stacks service and functionality is turned off. By default, SBS 2003 disables the MTA Stacks service and functionality. Some third-party programs install an Exchange connector that requires the MTA Stacks service to work correctly. Manually starting the MTA Stacks service may not resolve the problem.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.To resolve this problem, you must modify the registry to enable the MTA functionality. Before you start these steps, make sure that you have a good working system state backup. To resolve this problem, follow these steps:  Click Start, click Run, type regedit, and then click OK. Locate the following registry sub key:
