Windows Scheduler Error

Running a process (*.fmw) on windows scheduler. Getting the following error:

"Microsoft SQL Server Non-Spatial Reader: Trying to connect using SQL Server 2012 Native Client...

I have changed the default path to a shared directory and made database connections (reader and writer) public. The process works successfully on workbench but not on scheduler. What are other options to resolve this?

I also scheduled using the following batch file but that too fails:

rem #runas ms/omp_queries or it will not connect. (uses windows auth to DB's)
