I've been starting to play with this as well. Unfortunately I am not having too much luck. I can even be sure its picking up the unattend.xml file. Our current setup is RIS/ XP which we have been running for years. I have now added WDS to our ris server. We use a PXE boot to attach to the server. That portion seems ok. The base image we fed the ris server is there and does install to the client. However none of the changes we want are being applied. Also the machine does not join the domain. disk partition, etc. It seems like it is not using the setup file. Any suggestions?
