Yes, you need to put login1.bat in place of NTLOGON for that code to work.

In my organization, each OU has their own admin staff so when we migrated them to AD, we set their logon script only for their OU.
Code:

BREAK ON
$users = GetObject('LDAP://ou=Users,ou=bla,ou=bla,dc=yada,dc=local') 
$Users.filter = Split('user')
$loginscript = 'WKIX32.EXE KIXTART.KIX'
for each $user in $users
    if $user.scriptpath <> $loginscript
        ? "Current Script for " + $user.name " is: " + $user.scriptpath + " Modified to " + $loginscript 
        ;$user.scriptpath = $loginscript 
        ;$user.SetInfo 
    endif
next

you must remove the two semicolons for the script to commit the change.
