Hi Ya. This is on XP. I can run kix from the same folder, and I am sure permissions are fine if I created the directory and copied the two exe files as the use that I tried to run them as. I also get the results I expect when I run "runnas /?" The difference between the two users (the one that runnas works for and the one it doesn't) is that one is in the Domain Admins and Administrators group and the other isn't (the one that the command fails for of course).
