process.start rephrase

Do you have any idea why the following do not work?

(1) Process.Start("C:\\landon\\doaft.bat");
where doaft is
cd\
cd C:\program files\gl communications inc\aft
aft


(2) Process.Start("C:\\landon\\aft.exe");


Both do work from the command line!
Either way:

the process "aft" shows up in the task manager window but the task is not
really running....yes I tried maximize, etc
