vista "network and sharing center" "the parameter is incorrect"

Question

On Vista Home Premium SP1, when I try:

• Start
• Control Panel
• network and sharing center
• File Sharing
• Turn On File Sharing
• Apply

I get a very windows 95-esque dialog that says "The parameter is incorrect." With an OK button. No other explanation. Any ideas on what I should do enable file sharing? I get the same result if I try to turn on Network discovery.

Make sure the user account you are logged in with has a password on it. If it doesn't, crate one and then restart (or at least log out and in again). I had this exact problem with a Vista machine trying to enable Public Folder sharing and that is what finally fixed it for me.
