The manual tell something about the required files for Windows 9x clients:

[i]windows 9x clients must install both kix32.exe and two dynamic-link libraries (DLLs) call kix16.dll and kx32.dll.

If windows 9x clients are to communcate with the kixtart RPC service, an additional DLL, called kx95.dll, should also be installed.

Note: kx95.dll should only be installed if the kixtart RPC service will be used.
without the kixtart RPC service, kx95.dll will generate unneccessary network traffic and
delay the start of kixtart.

Greetings.
