Howdy. Here's the rundown. 1. My school has 20 brand new Dell Dimension 2400's (Celerons). 2. We have purchased Acronis True Image 8.0 Enterprise Server as well as Snap Deploy. 3. I have built an image "master" from one of the machines which I manually configured and have captured the image to be pushed across the network via Snap Deploy. 4. All of the machines (other than the image master, which is not in the group) have been completely wiped blank with Kill Disk. No hidden partitions, no nothing. Tabula rasa. 5. I have boot each machine using a Snap Deploy boot CD. They start up perfectly fine, connect to the deploy server, and then wait for me to execute deployment. In the management console, I see the IP address of each machine, so there's no doubt that they are connected. 6. When I execute deployment, several of the machines beep loudly and turn themselves completely off. The ones which do not shut down remain in the "downloading at 28%" state for about a minute, and then completely fail out. The error code I receive says "-1 (0xFFFFFFFF), host (IP) failed to deploy." 7. I have updated our version of Snap Deploy from 1,146 to 1,149. I also burned new boot CD's after doing this. 8. I have checked to see if this is a problem with the switch I'm using to connect all of the machines to our network, and I cannot find any fault with it. This is the second switch I've tried this with, and both are 100% brand new. 9. I have successfully imaged some of our other machine types (older model Dells, some Gateways), but these Dimension 2400's are giving me a serious problem which I cannot explain. 10. I have been in contact with Acronis tech support since last week, but I have not yet been presented with a solution. Unfortunately, because these machines lack a floppy disk drive, I am unable to download and run the diagnostic program which they recommend. I could put it on a CD, but then I would obviously have no way to collect the data from the diagnostic... I am almost tempted to take one apart, install a floppy drive, and try it then. Help, please? I really need urgently to get these machines imaged soon, as the school year is preparing to begin anew and many teachers are anxiously awaiting their new computers. Thanks!
