I haven't looked at it myself, how does it try to locate the server? If
it needs to use the name service (rpcss.exe), directly or indirectly, to
find it, it's very unlikely to work with wine right now.

It probably can't send any packets without knowing where to send them,
and if everything else is working, it probably needs rpcss to find out
(the local rpcss is usually requested to act on behalf of the client
instead of having the client contact the remote host directly, since
this lets rpcss cache such information).
Then again, it may be that not everything else is working.

I don't think native rpcrt4 and ole32 is necessarily enough; for
example, the TCP/IP stuff may not be implemented directly in rpcrt4, it
might depend on other dlls to provide protocol backends and
authentication services, and registry entries to identify them (though
I'm not sure). Also, COM is married to the registry and you'll probably
need a metric ton (as if there's any other kind of ton, heh...) of
entries to get DCOM to run with native ole32.

What does that have to do with netware? As far as I know, the security
principal is the backbone of the NT domain's and DCOM's security model.
