bhawver - sound like I need to get more information on NS, This is a company that is merging so we only have access to DS. The initial hurdle in to get SAV installed after the build, as soon as the PC reboots after joining the domain.
Timanator - I had hoped to just run it as a task after the build script but the build we have been presented with only uses altiris to call an hta file, so the task completes before the build has.
bhawver - I set up the task with conditions to check OS version and if SAV is installed and with these conditions I scheduled it to run every 15 min. Again it worked great for computers already added to the group but new computers added didn't pick up the task when scheduled task ran again.
Also what do you recommend deploying software using "Run Script" or "Distribute Software"
Thanks again for all the advice.
