Hi All this is my first post after much searching i can't find a similar issue so hopefully someone knows whats up. In any case. My issue is that with SP3 coming out it would be great to slipstream sp3 into our existing dell install disks that are sp2 ( at work sorry i didn't mention that earlier) i tried to use nlite as i use at home and it says it worked but when i go to install it it tells me that the CD key is invalid. I thought this was kind of strange so i went into the original dell disk and looked at the winnt.sif file and sure enough the key matches but it wont take it in the nlite created disk now that the disk is slipstreamed with SP3 any ideas how i can do this. I understand if it can't be done but i just feel like it should be no different than a regular install disk and i have read that people have got it to work but there is no mention of this problem before that i can find. Thanks in advanace! Chris
