All what I hade to do is changing JT location and then it worked.
Now I came across with other authorization problem, your help is appreciated.
The function\jt will pick up the current existing user id if you omitted it; is there any way to do the same thing for password also?

Through an official request to access control group I have created a “service account”. Before modifying the login script to add this account automatically to the power user group on all the user workstations, I added it manually to my PC then (while I already logged on with my own user id attiahia) I run the script with the service account & its password. Job has created but does not execute. Should the service account have admin privilege?

Thank you for any help.
