I meant that the functions did not return any information, but the environment variables contained a "-" as that's part of the script.

I used Sniffer to determine that info was being returned. I then checked the difference between that PC and other PCs running Windows 95 and 98 and I found out that netapi.dll was missing. Since it only caused problems with Kixtart, that unfortunately wasn't the first place that I checked. After installing the missing netapi.dll, Kixtart works properly.

Thanks for the support.
