Windows 2012 R2 Task Scheduler, call statement doesnt work

I have a Windows 2012 R2 server with a Task Scheduler entry. It executes a bat file nightly. In the bat file is a call statement to another bat file. The statements in the called bat file are not executing. When I run the bat file directly, they work. The task scheduler user is the same as the logged on user. I've tried different users. To debug, I skinnied the files down:

echo on
set ErrFile=C:\TD\CopyUsrErrMsg2.txt
date /t >%ErrFile% 2>&1
time /t >>%ErrFile% 2>&1
call BDSCopy2.bat
echo EndFile >>%ErrFile% 2>&1

BDSCopy2.bat:

@echo subfile   >>%ErrFile% 2>&1

When run directly the output file contains:

Thu 01/16/2014
09:27 AM
subfile  
EndFile


When run from the task scheduler, the output file does not contain the line "subfile". Please note that the production called bat file contains a lot of items; this scenario is just to demo the problem.

Am I missing something? How do I get the called bat file to execute?

Thank you.
