'net use' works in cmd window, not in .bat file

Win10 Pro, Version 2004, build 19041.804
(Suggestion to Microsoft- put a 'copy to clipboard' button on the WinVer window).

On my home network I have some servers and a couple of NAS drives. (Eight altogether). In startup I call a batch file to map them using 'net use'. Most of the time this works just fine. But once in a while, and with no particular repeatability (sometimes it's drive X, sometimes drive Y or one of the other net drives), the net use on the batch file fails. Most often with an error 67- unknown host, or network name not found.

In all fails from the batch file, if I open a separate cmd window and manually enter the net use command line, it works.

Here is my "top" bat file called from startup:

Code:

echo off
rem Call each network mount in separate batch files

rem Cleanup
net use m: /d /y
net use n: /d /y
net use t: /d /y
net use u: /d /y
net use w: /d /y
net use x: /d /y
net use y: /d /y
net use z: /d /y


:Continue
rem ---------------------------
rem Wait for the Network Service to be started
set /a x=0
:starting
Rem Send one ping to the router.  Write the results to a file.
ping 192.168.1.1 -n 1 > e:\pingtest.txt

Rem Search for unreachable in the file.

Rem errorlevel 0 is success, 1=fail (reverse logic, fail means the router is pingable)
if %errorlevel%==1 goto online

rem Wait one second and try again.

if %x% lss 10 (
  set /a x+=1
  goto starting
)
if %x% geq 10 (
  echo Network not responding after ten seconds.
  goto exit
)
:online
echo "Router is online"
rem ---------------------



rem Ping the NAS
rem Wait for the Network Service to be started
set /a x=0
:nucstart
Rem Send one ping to the NUC.  Write the results to a file.
ping nuc -n 1 > e:\pingtest.txt

Rem Search for unreachable in the file. 
c:\windows\system32\findstr.exe "unreachable" e:\pingtest.txt

Rem errorlevel 0 is success, 1=fail (reverse logic, fail means the router is pingable)
if %errorlevel%==1 goto nuconline

rem Wait one second and try again.
timeout /t  1
if %x% lss 10 (
  set /a x+=1
  goto nucstart
)
if %x% geq 10 (
  echo Network not responding after ten seconds.
  goto exit
)
:nuconline
echo "NUC is online"


echo on
call mntMverbose.bat
if exist "M:" echo M: online.
call mntNverbose.bat
if exist "N:" echo N: online.
call mntPverbose.bat
if exist "P:" echo P: online.
call mntTverbose.bat
if exist "T:" echo T: online.
call mntUverbose.bat
if exist "U:" echo U: online.
call mntWverbose.bat
if exist "W:" echo W: online.
call mntXverbose.bat
if exist "X:" echo X: online.
call mntYverbose.bat
if exist "Y:" echo Y: online.
call mntZverbose.bat
if exist "Z:" echo Z: online.

:exit
echo off
rem Show the connections
net use
TIMEOUT 30

And this is typical of my subroutine bat files (fake password):

Code:

rem echo off
echo .......... 
echo mntY.bat 
net use y: /d /y

rem ATA drive in Nuc
IF EXIST "y:\" goto xit
net use y: \\nuc5\mntD /user:nuc raspberry /y 
IF %ERRORLEVEL% EQU 0 goto xit

rem Try deleting the map and try again
net use y: /d /y 
net use y: \\nuc5\mntD /user:nuc raspberry /y

rem sleep 5s
:xit

Any solutions would be appreciated....

It can take some time to see pcs in a network and the master browser needs to be up to date. If you use IPs it should solve the problem as you wont need to wait for name resolution to kick in

Thanks for the input. You may be on to something, I'll try putting a short delay between the subroutine calls.

The problem with using discrete IP addresses is that Windows does not allow me to use the same IP for different mount points. For example, I have an NAS folder and a Mediawiki database that are both on 192.168.1.54 and I can't use
'net use t: \\192.18.1.54\storage'
then later
'net use w: \\192.18.1.54\wikimedia' .

If I do, I get: System error 1219
ERROR: "Multiple Connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

The solution was to add a few entries for the share server in the hosts file, C:\Windows\System32\drivers\etc\hosts 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

So,
'net use t: \\nuc1\storage'
'net use w: \\nuc2\wikimedia'
does not give the 1219 error.

This is why I have hostnames for the IP.
