I've got exactly the same problem. Used different machines, VMware, etc. So it can't be a hardware fault. I'm not behind my computer, so I can't post my winnt.sif, but it's a DVD with XP SP2RC1, Office2k3 and a bunch of small programs like Symantec AV corporate, Winrar, etc. All unattended. Anyone has any idea what could cause this? It happens áfter all the files are copied to te HD (the XP install and the $OEM$ files), when it tries to reboot...
