I'm not trying to blame anyone for the problem, and I HAVE posted in the nLite section on this. [Look for the "Missing EULA.txt" post] I've grabbed the microsoft tool for creating the winnt.sif file and I'm in the process of trying that. I've compared both .sif files and noted a few discrepancies between microsoft's and nLite's .sif files. Also, the cd I'm using is an MSDN Windows 2003 cd, with both Standard and Enterprise versions on it, and it's employing some TOC tricks to keep 1GB of data on a 624MB cd. Who knows what this may be doing to the install process. [edit] I should probably clairify on MSDN cd. All I'm trying to do is create an SP1 slipstreamed server cd that prefill's my comapny's information. The original MSDN cd I have to base all of this from, has both Enterprise and Standard versions on it. Properties of the cd show that it's using a total of 624MB, yet if you do the properties of each install folder, each folder shows 545MB of data, which of course, isn't possible on a CD. I believe MS is doing some TOC tricks to have a single file appear to be in two different folders, or in this case alot of files appearing in two different places.
