Well... my next logical question is... why is the NETAPI32.dll in the netlogon directory? Have you tried just renaming the file to see if the problem corrects itself? In my logon folders I have nothing but the kix32.exe and the scripts.

Also of note, I do not use wkix.exe.

I'm not sure how this relates, but here is a (very old) thread that shows what Kix is looking for in terms of DLLs. http://www.kixtart.org/forums/ubbthreads.php?ubb=showflat&Number=96858#Post96858. I have never once added these files to a machine, so obviously they are part of a standard Windows release.
