I can RIS WinXP SP3 fine, but if I try to RIS Win2K3 SP2 it gets as far as "Setup is starting Windows" and just stops there.

The same drivers are used, the same ristnrd.sif is used (changed Productkey only).
The RIS Server is Win2K3 SP2.
Images used are flat, unattended install types.

Anyone know a solution or is there something wrong in my sif file:

;remember to update ristndrd.sif in Images\Windows folder
;SetupMgrTag
