Permissions på et share - windows 7

Hejsa

jeg har fundet nedenstående kode, som opretter permissions til et share. Jeg kan godt få det til at virke - bortset fra at brugeren alligevel ikke kan tilgå sharet. Brugeren dukker op i listen under *folder*>properties>sharing>advanced sharing>permissions - og med de rigtige afhakninger. Brugeren findes ikke under *folder*>properties>sharing>share - hvilket undre mig lidt.

Nogen gode ideer?
