Scan to SMB not working with PC hostame in the template of the address book

In some customer networks, on Versalink products, it is impossible to work with a smb scan  in the address book if you enter the host name of the recipient pc.There is a network error.
If we enter the IP address, it works.
I also found that in this case, if we want to scan using network discovery, it finds nothing and incident mark.
This is annoying for mobile PCs
Do you have an idea?
