I have a program I would like to install on all machines on our NT lan. I
have written a program  using UDP that can send the commands to install the
software from the domain controller but an administrator must be loged in at
each workstation for the software to be installed correctly.

I know this can be done (I recently got McAfee Total Virus program and it
can install itself across the lan with no one logged in).

Anyone got any ideas on how to do this?

Thanks
