In your case we suppose you are using a wrong set of kixtart files, or
the system creates a mix-set of it.
With our script version.kix on our site http://home.wanadoo.nl/scripting
you can check the correctness of your set.
Another possibility is to locate all kix32.exe, kx16.dll, kx32.dll & kx95.dll files
on your clients:
remove
and
reinstall a new set.
Reinstall is possible with our package f.e. kix363update.exe. Possible
code for your LOGON "BAT" file can be:

code:

---

  %0\..\kix363update.exe /q
