scheduling jobs with ‘at’ command on NT

I am struggling to schedule two job on windows NT, patch 5 with at command. I am managing to schedule but jobs can’t run at all. Is there any tip, or am I applying the format wrong? Here is the command to shut down the database and startup every dayexcept sunday
1. Command one:
at 23:00 /every:M,T,W,Th,F,S cmd /c “c:\bat\pts_shut.cmd > c:\bat\shut.dat”

2. Command two:
at 06:00 /every:M,T,W,Th,F,S cmd /c “c:\bat\pts_start.cmd > c:\bat\start.dat”
