RE: network redirector IRP_MJ_CREATE with FO->Related--FileObject != NULL

Alex,

Yes, this works, but not into a network redirector (since you cannot, in
general, export a network volume via SRV.)

SRV (the CIFS file server on Windows NT/2000) does almost all of its I/O
operations relative. Win32 applications do not because their API is pretty
much restricted to whole paths only (there’s no way with CreateFile to
specify an already opened directory, at least not as I understand it.)

suddenly i remember our good old ZwCreateFile(…) with
ObjectAttributes->RootDirectory == SOME_PREVIUOSLY_OPENED directory object.
Of course i think i need a mapped network drive for this test, like G: =>
\remote_computer_name\share-name

will this result in the test case?

thanks & regds
alex
