1) the task squence properties 'os info' tab has the edit sysprep.inf button, there is also already a sysprep.inf file within the wim file I captured via mdt, so which is used? both (merge)? 2) Here is my theory on the when/how the unattend.txt and sysprep.inf files from the task squence properties 'os info' tab are used. PLEASE correct me if I am wrong. The unattend.txt is used during initial unattended installation of the OS by mdt, the sysprep.inf is copied to the target machine before sysprep is run.... so after a wim is captured of this and you make a new task sequence to deploy this custom wim the sysprep.inf file that is already in the wim is used and so the unattend.txt and sysprep.inf from the task squence properties 'os info' tab is simply not used? generally confused on which settings where take precedence when they exist in more than one place... like sysprep.inf in either the task sequence or the wim, or the task sequence properties/variables that could be supplied via the deployment wizard or set by your own scripts?

Hi Unattend.txt is being used at first install (when you create your image) sysprep.inf is created at the end of the image creation by mdt and inserted in the captured image with settings (new drivers path, etc that you define). You can override specific settings at deployment by using a different sysprep file (this time the original will not be used) Note that unattend.xml is the vista/win2008 sysprep file. hope that it helps

bpostiau, I dont think you answered the question. When you build and capture a windows xp WIM, the sysprep.inf in the capture task sequence is used and added to the wim. When you deploy the captured wim you have another sysprep.inf in the deploy task sequence. (this is also used as if you start to change things like product key this is reflected on the machine that you are deploying to. Can someone clarify this please.

If you have a Create and a Deploy then the sysprep file that will be used is in the Create structure. I think thats what you are asking anyway

I posted this to an MS newsgroup also. Here is a copy/paste of the reply I got. ----------------------- 1) the task squence properties 'os info' tab has the edit sysprep.inf button, there is also already a sysprep.inf file within the wim file I captured via mdt, so which is used? both (merge)? Correct. If no sysprep.inf is in the wim than the entire sysprep.inf from distribution\Task Sequence directory is copied to machine. If they are in both places a merge happens. 2.)so the unattend.txt and sysprep.inf from the task squence properties 'os info' tab is simply not used? False The script that makes the merge happens is "ZTIConfigure.wsf." It reads ZTIConfigure.xml and based on all the properties as defined there a merge occurs. Values which are present in the sysprep.inf from the distribution directory win. If you open the xml file look for "mapping id" to the the values checked. In this way you can manage the sysprep.inf from 1 central location. Ultimately, you could mount the captured wim with imagex and remove the sysprep.inf from the image but this should not generally be necessary. XP needs sysprep.inf tp be present so that MassStorage drivers will be included when that image is captured. Dave Guenthner [MSFT] -------------------------------
