When I try to run KIX32 on 95 machines I get 'A required .DLL file, NETRAP.DLL, was not found.'

KIX32.EXE, KIX16.dll, KIX32.dll, KIX95.dll are in Windows\system directory. The KXRPC service is loaded and running on ABCCS01. I have tried a KIXTART.INI in the same directory with
[KXRPCMapping]
Default=\\ABCCS01
in it
and I have tried
SET KXRPC=\\ABCCS01 in autoexec.bat

without success.

I am sure this has been asked before but I would be grateful for some help.
