Just found this out when developing my program NextHooker (https://github.com/Artikash/NextHooker). See host/pipe.cc and https://github.com/Artikash/NextHooker/commit/c431cda7d7961c9799da928aff673c....
Fails with error code 123 (ERROR_INVALID_NAME), returns INVALID_HANDLE_VALUE. Works fine on Windows of course.

--- Comment #1 from Sergio Gómez Del Real sdelreal@codeweavers.com --- I don't think this is a bug in Wine; documentation explicitly says:
"The pipe server cannot create a pipe on another computer, so CreateNamedPipe must use a period for the server name, as shown in the following example.
\.\pipe\PipeName"
Documentation for CreateNamedPipe is also clear about the form being restricted to "\.\pipe<pipename>":

--- Comment #2 from Zebediah Figura z.figura12@gmail.com --- ??\ is the global object namespace. The documentation is more concerned about forbidding cross-machine pipes, and doesn't explicitly say that you can't use the global object namespace.
In any case, actual testing trumps the documentation, and testing does show that ??\ works (although not on XP).
Problem seems to be in our implementation of RtlDosPathNameToNtPathName_U(). I'm taking a look.
