Bat file doesn't log when running from task scheduler?

Question

I made a bat file which restarts 2 services, and I have it run in task scheduler. If I run the bat file normally, I can see it logging in current directory as the bat file. But if I run it through task scheduler, I can see the bat runs, like in services window, I can see the services restarting, but it doesn't log anything.... Does anyone know what the issue is?

This is on windows server 2008 r2 64-bit.

Thanks

When you run things in the Task Scheduler, the working folder (by default) is %windri%\system32. So any files created by the task, that don't have a path specified, will be written there (or at least it will attempt to write them there).

To avoid this, specify an absolute path in your SET logfilename_sp_fix="SPSearchFix.log" line.

E.g.: SET logfilename_sp_fix="c:\temp\SPSearchFix.log

And ensure all users (or at least the user the task runs as) have write access to that chosen folder.
