How can i reshare my files after my server crashed

I have a server and NAS Qnap, last time my RAID 5 crashed (2 disque) at once, i had shared files, but because my server crashed i cant access them, now i’m trying to create local user on my NAS and give it permission to the files i want to access, but when i try to add a map network driver it wouldn;t work,
this is the error message, and i can only connect to one file only

No error shown.

@Chanez:

The RAID is on the server (which is what system?) or, on the QNAP NAS?
