Table File (virtual table)

Hi there,
I'm freaking out with a problem that I haven't solved yet.

It turns out that I'm filtering the table File (virtual table) with 'X:\SHAREDFOLDER\' (it's a shared folder) but unluckily the table isn't able to load any record (I mean the folders and files of that shared folder). On the other hand, if I try to do it with 'C:\MYLOCALFOLDER\' works perfectly.

I've checked the properties of the user and has total access in that shared folder. My version is NAV 2016 and the service DynamicsNav90 is start by NETHWORK SERVICE.

Could it be that virtual file table crashed with shared folders??Or...??

Thanks
