There are many scripts are available over the internet for creation of home directory but it is risky to use script without proper test. But I believe following methods are simplest way to create home folder for users.
Open ‘Active directory users and computers’ and select multiple users by ctl+A or Shift+click (if you have too many users you can certainly begin with OU by OU).
Select any available map drive name (eg. U: or H:) then server share path name. (e.g: \\servername or NAS\sharedfoldername\%username%)
