Verify the connectivity to the backend database
One way you can do this is through a UDL file.  Here is how to create a UDL File to test SQL Connectivity:

How to create a UDL file to test the connection to SQL Server

  2. Change the file extension to UDL (TestSQL.UDL)
  3. Open a Command-Prompt where you right click while holding the Shift button down to select Run As.
    1. You want to run it as the FIM Service Management Agent Account
    2. Or you could log into the machine as the FIM Service Management Agent Account
  4. Double click on the TestSQL.UDL
  5. On the Provider Tab ensure that Microsoft OLE DB Provider for SQL Server is selected
