Restoring from a network drive

Question

Using SQL Server 2008R2, I am trying to restore a .bak-file from a network folder (on a NAS)
I keep getting the following error:
Msg 3634, Level 16, State 1, Line 2
The operating system returned the error '1317(failed to retrieve text for this error. Reason: 15105)' while attempting 'CreateFileW' on '\\<IP HIDDEN>\rppt\backup\myDB.ndf'.
Msg 3013, Level 16, State 1, Line 2
RESTORE DATABASE is terminating abnormally.
According to my Google searches, error Message 1317 means 'There is no such user'
I have set the SQL Server service account to a domain user. The user has also full privileges to the network folder I am trying to access

Answer 1

no, the goal is to restore the .bak file into the same NAS. The command is like this (note that I had to change some of the names to anonymize the command)
RESTORE
