failed to locate kx16.dll! Please make sure kx16.dll is present in %path% or %windir%

Srs,

Recently I upgraded my version of Kixtart to 3.60 and something is going wrong with this version of Kix in ny netowrk. About 20 desktops, running W95, started to show a error message during the logon process. The error is: KX16.DLL COULD NOT BE FOUND IN %WINDIR% OR %PATH%.
The desktops was running kix32.exe from the netlogon folder.
I tried to copy the kix files to the windows\system folder, with no result.
I tried to edit the path in autoexec.bat, adding the follow: c:\windows;c:\windows\command;c:\windows\system, with no result
I tried to run the Windows 95 bug 2000 fix, with no result

What is happening?
