IF you have either LAYOUT.INF or SYSSETUP.INF in your signing directory. Deltacat will not sign these files which must be signed in nt5inf.cat. Let deltacat run then do the following: 1. Copy nt5inf.ca_ to your signing directory from wherever your are installing, e.g. \\ntbuilds\release\usa\latest.tst\x86\fre.wks, or, e.g. e:\i386. 2. Make sure you have the most recent updcat.exe 3. Run infsign [directory], e.g. infsign c:\bin When complete, run winnt32 /m:[directory]
