I may be confused so I will state the question as I see it and someone can correct me as needed.
" I need to be able to name the PCs that I am imaging so that once they are finished with the provisioning process they show up in LANDesk with the name I chose."
We use Bare Metal config for the new PCs and simply drag them into the OS Provisioning task. I then have %Computername% in the Device name within the image file. LANDesk has added the portion that you are interested in automatically within the script file. Look for the example Windows 7 script(s) used in Roy Meyer's post on setting up OS Provisioning. I used them and had good results.
An excerpt from the base of my script is below. Remember to only use a 64 bit unattend with a 64 bit release.
<settings pass="specialize">
<component name="Microsoft-Windows-Shell-Setup" publicKeyToken="<SomeNumberYoursWillDiffer>" language="neutral" versionScope="nonSxS" processorArchitecture="amd64">
<ComputerName>%ldHostname%</ComputerName>
</component>
I can provide the entire script if required.
