We did a short analyze what is going on with a kix32.exe call.

• kix32.exe
  means
  - first try to find a script kixtart.scr in your working directory,
  which doesn't mean "it is your NETLOGON directory".
  - secondly it will try to find a script kixtart.kix also in your
  working directory.

  conclusion: it only search for a script in your working directory. first with the
  .scr extension and later with the .kix extension.

• kix32 x:\scripts\your_script

  it will search first for the script your_script.scr and secondly for
  the script your_script.kix in the directory x:\scripts.

• kix32 x:\scripts\our_secure_script.txt

  it will not search for a file, but try to execute specified file. the extension
  of it isn't important. the contents must only be kixtart code.
  

please change your logon.bat file to

code:

---

@echo off
 dir /b >>c:\kix-info.log
 %0\..\kix32
@echo off

---
