If you want to take a snapshot of an entire machine, including installed applications and so forth, try using a combination of SysPrep and
G4L.
1. Create a new ibay on the SME Server, and allow FTP access from local networks
2. Prepare your template machine with all the applications and settings
3. Download the Windows XP SP2 Deployment Tools (there are no new tools for SP3)
4. Create SysPrep.inf as per
http://support.microsoft.com/kb/3025775. Run SysPrep.exe; the computer will then shut down
6. Boot from the G4L CD on the template machine
7. Use G4L to copy an image of the template machine's hard drive to the SME Server ibay via FTP
Once this is done, to deploy the image on the other four machines is relatively easy.
1. Boot from the G4L CD
2. Use G4L to copy the image from the ibay
3, Reboot, and let SysPrep do its work
