After you have unzipped SRPC*.ZIP you will find the binaries in the directory "bin". You should copy at least oncrpc.dll to the "system32" directory. Now you can run pm_ascii.exe from the "bin" directory as console application, but the "real" NT way to do a daemon is as a service (this does not work on Windows95).
To install the portmapper as a service copy "portmap.exe"also to the "system32" directory und use "inst_pm" to register it (see usage). After that you can start and stop the portmapper from the "Services" control panel.
If you want to use symbolic names for your rpc services you should create an "rpc"-file in the directory "%SystemRoot%\system32\drivers\etc\". You can start with the file provided in the "etc" subdirectory.
Perhaps you might want to recompile the libs, the dll, and the example-application. If you have MS Visual C++ installed, you can use the workspace file "oncnt\oncnt.mdp". It contains all the components of ONC RPC as subprojects. If you prefere a shell interface, a "make.bat" in the main dir should also do the job. In both cases the "rpcgen" utility calls the MS C preprocessor to do its job as it calls the cpp on Unix.
What you need to know is, that a client program like do_cou.c has to call rpc_nt_init() and rpc_nt_exit() around the rpc action (because of the winsock initialization). Make sure that you have WIN32 defined, the "rpc" include directory in you include path, and rpc.lib in your linker line when you build an RPC-application. Be sure that exactly one version of "portmap" (see above) is running when you run your RPC-application.
Look into the "test" directory for a simple application: a "counter-server"(cou_svc.exe) and simple client (do_cou.exe) that calls the server and does some counting.
All run-time components of ONC RPC for Windows NT write their error-messages into the application log (clnt_perror() has been changed as an NT application does not always have a stderr stream). Look there first if something seems to fail.
ONC RPC for Windows NT does currently not support the authentication interface.
