WDS Legacy (RIS) and XP SP3 Flat image
We currently have an XP only environment, and are using WDS in legacy mode(RIS mode) to deploy XP SP2 from the RIS server. This currently works fine, and I have some new laptops and desktops to setup for September.
I can currently setup the new laptops and desktops with XP SP2, both flat and with drivers (I try and deploy all apps through GPO and MSI).
I can also update these images with SP3, riprep them and have an updated SP3 image with drivers for the new laptops and desktops.
What I currently cannot do, is create a new flat image that contains SP3. I have managed to slipstream SP3 into a SP2 CD, but when I try and add the new image to \\risserver\REMINST\Setup\English\Images\, using RISetup, it just says "media fail, cannot use Upgrade version".
From what I have read, I think this is because I currently have an XP2 flat image (with a risstnd.sif file). Do I need to remove this (or put all the XP2 images into a different location or folder named SP2_Images or something) and create a fresh Images folder with no images in, then create a new SP3 flat image, using Risetup?
