So there's nothing in the documentation or the KB or even on these forums about the Update Task with a schedule of: On Dialup
How soon after the dialup does it start?
When does it start (like after it detects the phone is dialed, after its connected, or after it has connected, but has gotten an IP address?)
Well, all that depends on the settings that You have defined.
From the VirusScan Console:
Right-Click 'AutoUpdate On-Dialup' > Properties
'Task' Tab >
review settings, change as needed
check that it is Enabled
'Schedule' Tab >
'Run Task' > On Dial-up
'Enable Randomization' > (I use 5 minutes to give the user a chance to 'login' successfully before loading up a dial-up connection.)
Hope this is helpful; post back with additional questions.
