I made a **
automatic-network-drive connector
** using a batch file.
Suddenly there was a networkdrive called "Data for Analysation", and yeah with the double quotes it works proper!
looks a little bit different but works:
net use y: "\\share.blabla.com\Folder\Subfolder\Data for Analysation" /USER:domain\username PW /PERSISTENT:YES
Thx for the Hint :)
