This is probably the problem. I just wrote a lengthy explanation of
what happens in case of public key authentication, see:
http://cygwin.com/ml/cygwin/2006-07/msg00577.html
You're getting the same problem in case of rhosts authentication, it
all boils down to "password-less authentication".
Your case is not exactly related but it doesn't hurt to read this first,
just to get an impression and maybe a coffee break.
I can't explain the error code 0 right now, but I assume your problem is
the handling of user rights related to global objects. Reading
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/termserv/termserv/kernel_object_namespaces.asp
gives a bit of insight into the general problem.
I have to be able to reproduce the problem, which I can't ATM.
As a workaround try giving the "Create global objects" user right
to the sshd_server account alone. If that doesn't work, add the
"Create global objects" right to the users login in through rsh.
Please report back the results of both tests.
