--- 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.
