Mcafee “DAT” file Autoupdates

I run a Novell 5.0 Lan of about 50 people and use Mcafee Virus Scan 4.5 on all my workstations. I have the Autoupdate on my station set to check Mcafee for updates and save a copy of the update to a network shared folder. I have pointed the Mcafeeautoupdate feature at all workstations to install updates from the shared folder and set the update to start 2 minutes after booting. The problem I am having is people are not logging into the network in the 2 minutes so the update feature can’t find the network drive shared folder and therefore the workstation does not get the latest update. I wondered if anyone knew how to configure the update in my global login script?

thanks,
Rob
