Check for Known or Unknown Computer

Hi all,

So, the challenge I have is to cater for both known and unknown computer deployment.

I have one task sequence advertised to two collections (Unknown Computers and All Desktop Clients). Obviously this means two different advert IDs.

I have UI++ configured to launch as a prestart command within my boot image.

What I need is a method of checking whether the machine is known or unknown at this stage in order to set the correct %SMSTSPreferredAdvertID% - so as to avoid an engineer having to click through any of the standard SCCM interfaces.

I was able to check for this when I was running UI++ in test as a step at the beginning of the task sequence using "Condition='Left("%_SMSTSMachineName%",6) <> "MININT"'/>", but running as a prestart command this variable doesn't appear to be set yet.

Is there something else I can query for, or another method that I'm missing?

Thanks
