Yea the work around really isn't feasible here as the domain account used to start the SMA when the machines boots for the first time fails to load because the machine didn't get joined to the domain.
I've actually tried sysprepping a few image sets now to no avail..The way I've currently worked around this is using a custom sysprep file which has the correct domain information manually entered in it.
The generated sysprep file from Symantec is using the @identification token, which I can only assume has the incorrect information.. This is why known machines will image fine using the "generate sysprep from inventory config data" and the new machines won't... Because for the new machine it doesn't have any inventory machine config to go by.

Any idea where the information for the @Identification token is being pulled from? I didn't see it in my general list of tokens..(which could also be the problem as it doesn't actually exist.)
