Hi there ,

Today a customer requested an interesting scenario about selecting a preferred deployment when deploying multiple TS to a single collection:


You have made a few task sequences available thru PXE boot and enabled unknown computer support . You set all your deployments to available , not required.
When you start your OSD deployment , you will see the few task sequences sitting there and waiting . This is a correct behavior.

The customer likes to see the following behavior:

– one of the task sequences made available will be started automatically after 30 seconds  if none of the other TS are selected.

This will help them to avoid the import computer information part as they stage thousands of machines over one weekend and there process is that the computer name is generated from their CMDB tool after the mac address and serial number is scanned. Then we extract that information and push it into TS variables.


You can define a deployment in a prestart command that overrides existing deployments to the destination computer. Use the SMSTSPreferredAdvertID task sequence variable to configure the task sequence to use the specific Offer ID that defines the conditions for the deployment.
