Searching a file on a shared resource

Hello,

I need to search a file in a directory on a shared resource

I use for this purpose the Windows Searching Utility by :

- either right clicking on the mouse from the root (or one of the first

level) directory on the shared resource,

- or clicking on the magnifying lens icone on the upper bar of the explorator

It always and systematically fails with an error, sthg like "no file found

...." even if i test it with a file which does exists (i.e. whose name i have

copied and pasted)

On theother hand this searching utility does work on a local disk or my

personnal shared resource (such a resource is dedicated to every worker in my

workplace)

Woh can i make it work ?

Thanks a lot for your answer !
