After repairing or installing FAX on SBS 2008
When we try to add Fax account Under Tools in Windows Fax and Scan
Click on connect to Modem
we get the error

Cause

The error message is misleading
Even though the user maybe a member of the SBS Fax Administrators group.
This due to User Account Control 

Resolution / workaround

Launch the Windows Fax and Scan as the administrator
we are able to complete the configuration (i.e. Run as Administrator)
