I am also having this problem. Using Nlite 1.3RC2, boooggy's WMP11 integrator and Ryan's 2.1.6 pack. I have the computer name declared in the WINNT.SIF file yet the install halts and waits for input (press enter). I can post my .SIF file when I get home from work. Apart from this problem, my XP install CD is flawless. This problem occurs on real hardware and virtual machine.
