Is the above possible?

I'm writing Winbatch scripts to automate updating workstations at my
company. We are trying to do a lights-out upgrade with multiple reboots.
The script will implement auto-login, update the NetWare client and ZEN
agent. Auto-login will be then turned off.

I've manually submitted a job to run my script, but it won't run while
the w/s is at the login prompt. I get a "0x0" result, which means the
scheduled task launched, but setupnw.exe via acu template most certainly
did not run.

Is it possible to run the NWC V4.90 install from a scheduled task while
the workstation is logged out? Does the client install need a service or
process running that is not present while the w/s is logged out?

Any help appreciated.
