I figured I could have one computer set as a server and all others set to boot off the server, this way they would boot and receive only when the server computer was powered on. My problem is that each computer will have to have a unique name. If I broadcast the same image over the network how can I change the computer names without sitting at each individual computer, I'm trying to make this completely automated.

In my lab I do the image, and have a program in the startup that checks the machines MAC address, and looks up a file, and then modifies the registry and reboots the machine. This way the machines then have a uniq name... Another option is a program called wsname that does something similar, but it uses the ip address. How do the machines get there IP addresses? What OS are you running? As a note: I recently had another teachers lab that is getting hit by viruses the get past the norton antivirus from flash drives. I split the drive into a 40GB XP partition, and an linux ext2 30GB partition using gparted. Then I made an image of the XP partition onto the ext2 partition using g4l with ntfsclone option. Makes about a 6GB image file, and then can be restored in about 6 minutes from the ext2 partition. Have setup grub4dos on the XP partition, so the boot gives option to boot windows or use grub. The grub menu has g4l, udpcast (send), udpcast (receive), and udpcast. The g4l can be used to make new images or restore a single machine. The udpcast options can be used to image the whole disk to all the other machines. Update one system, and make new image, then udpcast send that machine to all the others. My own lab has machines with 98, XP, and Linux, and I have the same thing, but using the regular grub to give the boot menu. Don't know what kind of drives and how much space you are using on the disk, but that might be an option.

I was recently made aware of the UDPcast facility. I am impressed by its simplicity and cross- platform interoperability. 1) What brought me to you is the search for a networking tool that I have identified for many years. It appears that if we can configure the front end of the UDPcast (just the initial phase of "broadcasting" and "listening" part) to provide a near-real time overview of all active devices on a network, we can empower mass consumers with a pieced of crucial baseline information., that is, the instant health status of their SOHO (Small Office Home Office) or Residential network, even without an IT manager nor any technical know-how. 2) I am a system engineer trained in hardware designs emphasizing traditional RF and telephony. I can identify potential new applications based on capable technical ingredients within an existing product. However, I am not good at the actual detail implementations, especially software. Since UDPcast is the result of an open source effort, I thought that it would be prudent for me to check with you to see if anyone would like to work with me on the idea that I have, so that the outcome can benefit the general public. 3) For those interested in what our team has accomplished up to now, please have a look at a set of overview slides: http://www.avinta.com/phoenix-1/home/ProjectPhoenixPrimer.pdf With basic network architecture and transmission capabilities identified for satisfying MaP (Mom and Pop) type of users, we have been looking for the next level intuitive building block. That is, with so many devices possible on a SOHO network, how could an owner get a concise visual summary of which ones are currently online? Once this is provided, MaP will have a clear reference line to deal with potential cause of network issues, either by doing their own "unplug and swap" substitutions or having enough confidence to deal with techsupport personnels. 4) I will be glad to write then submit a product specification type of document describing details of my thoughts as an outline to begin more specific discussions, if anyone would indicate the interest in working with us. As implied, the end product of this effort will be a utility distributed to mass consumers for them to enjoy network services because they will be able to "manage" the very basics of their own network. I look forward to any thoughts and comments.

(other than ditching the nic express of course :p ) Well, ditching Windows comes to mind... :-) Indeed, windows is often unreliable/unpredictable in these subtle performance aspects, and provides few (if any) diagnostic info.
