Below is roughly the order of events after starting Emacs when netlogon
is running:
- 2~3 min - GUI shows up, Emacs welcome screen (*GNU Emacs*) is not
loaded yet. Window elements (menus etc.) are unresponsive.
- 6~7 min - Welcome screen shows up. Commands can now be run, GUI is
responsive.
- Post startup, if w32-get-true-file-attributes is:
(a) nil: file operations are responsive albeit 3-4x slower
than when netlogon is not running i.e. not instantaneous.
(b) default: extremely sluggish response. File operations
(opening of files, filename autocomplete or dired etc.) each take 2-3
minutes or more.
By startup failure I imply the performance is so slow and unpredictable,
one is unsure if Emacs will actually show up. No error message is
displayed as such. I'm actually out of patience by this time.

Yes, the same problem occurs with the latest alpha build
'emacs-20120917-r110062'.

Yes.
