IFS Database Task error because no found path

Hello, 

I would to shedule a task pour generate a FEC XML.

in the first picture we can see a parameter of my reporting.

My problem is the PATH parameter. I put the output path of my file 
.xml

When i run my task , IFS can’t find the path \\vm-data-grp\bureautique\Extractions\IT 

i try to make or not the name of xml , same result.

Is the syntax good ? 

I can go to this path too when i’am connected since database serveur. 

I don’t know why the path is wrong...

Thank you

For information i execut this process in the database task.

The folder exist : 

Info IFS V10 , udpate 5.
