Altiris 6.9 deploy image - using unknown Unattend file?

In our environment, we have two Altiris 6.9 servers.

I created a Windows 7 image and am able to deploy it with success, in that, all of the drivers load accordingly from the unattend file.  I can verify that the correct unattend file was used by navigating to C:\Windows\Panther on the freshly-imaged machine.

On the second server, however... if I use the same image and job, the deployment is fine, but no drivers are loaded.  On this machine, if I navigate to C:\Windows\Panther, it appears to be using a completely different unattend file.

Can anyone explain how this may be possible, and how I may resolve it?

Thanks!!!
