Windows 2008 task can not schedule bat file

I also tried system account, that other tasks are running, but also doesn't work.

...but did you check the Local Security Policy?

Yes, I have there:

Administrators, Backup Operators, ftp_subacount, IIS_IUSRS, IME_ADMIN, EME_USER, Performance Log Users, psacln

How did you specify the command line in the batch job?   I'd expect to see something like:

c:\windows\system32\cmd.exe /c c:\somepath\somebatch.bat

I have tried both ways, your way and the other way. The other way is just to call the batch, it works on windows 2003, the batch calls cmd.exe by itself.

I tried using the /c switch also, yes (I don't know what it is).

Do an "export" from the Task Scheduler and post the XML output here for us to see

I really cannot understand it, now it works... Using your way. The same line was in before and didn't work. Anyway, thanx.
