NET USE in a batch file- sometimes works

Windows 10 Pro
I have a batch file where I map my net devices, mostly Samba shares from my Linux servers.
(I know you don't like to see snippets, but the bat file is over 300 lines long.)
Basically, I have a function for each drive to be mounted:

Code:

:mntXrem Shared folder on NUCIF EXIST "x:\" goto xXnet use x: \\nuc4\hshare /user:nuc raspberry /yIF %ERRORLEVEL% EQU 0 goto xXrem Try deleting the map and try againnet use x: /d /y >NULnet use x: \\nuc4\share /user:nuc raspberry /ysleep 1s:xXgoto:eof

At least one of the drives, seemingly at random, will give me a "name not found" error or a "System Error 5" (AKA. BSOD for NET), but when I open a CMD window and manually enter the net use line, it works. Sometimes simply repeating the bat file corrects the problem.

Can anyone suggest why running the net use from a bat file could fail when the same net use in a cmd window connects just fine?

<And how do I properly post code?>

The fool proof way is to use IP not name you would have to set static IP or reserve it on the router or you could put the name in the host file. The problem is name resolution

Thanks.
Windows won't let me use the same IP for different shares. I forget the exact error. I fix this with multiple names in my hosts file:

192.168.1.54 nuc1
192.168.1.54 nuc2
192.168.1.54 nuc3
192.168.1.54 nuc4
192.168.1.54 nuc5
192.168.1.54 nuc6
192.168.1.54 nuc7
192.168.1.54 nuc8
192.168.1.54 nuc9

Each name is only used once.
