I have copied all necessary files (kix95.dll, kx16.dll, kx32.dll, kix32.exe) to netlogon share on DC's servers, and replace file kxrpc.exe with the new one and restart Kixtart RPC Services. It works fine with Windows NT 4.0 and 2000, but failed on Windows 9x with the following error: "Kix32.exe has perform an illegal operation...". Any idea?
