I used AutoStreamer to slipstream SP4. Extracted the ISO and added the OEM folders. Then used nlite to add the hotfixes1. Burnt a bootable CD-Rom it all worked well till I got to the Product key,I originally added it to the winnt.sif file A error box came up "Unintended setup is unable to continue because of a setup parameter specified by your system admin or computer manufacturer is missing or invalid........." I entered the product key and it didn not continue so I hit enter a couple times and it hung so I rebooted and when the dialog box came up again I entered my prduct key again but this time with the last 2 reversed and it came up as invald product key. So I entered my product key again and it stopped again and then hung Any ideas what is going wrong
