Ked to ma fungovat aj cez ucty , tak to ma fungovat ...
Vygooglil som mozne riesenia:

1. Map the drive using this syntax at the command prompt:
net use X: \\Hostname\Share /savecred /p:yes
It will then prompt for a username and password, which will be saved and will not prompt even after a reboot.
You can also add the credentials by opening Start → Run → control userpasswords2 → Advanced → Manage Passwords.
This feature exists on Windows XP and later.
(neskusal som)

2. Napisat vlastny .bat subor, kde sa po kazdom reboote (logon -e) bude mapovat dana jednotka
@echo off
echo --------------------------delete map drive all------------------------
net use * /delete /yes
echo ------------------create drive --------------------------------
net use m: \\172.16.0.136\Source /user:aleg\masr masr2006*
net use n: \\172.16.0.136\scanner_bat_test /user:alwq\4288044 masr2006*
echo -------------------------------------------------- -
